simplebus pnp: Do not generate pnp info is the bus status is not okay

if the status isn't "okay".
That means that loading the module will load but not attach as it checks
the status in the probe function.

Align OF_getencprop_alloc API with OF_getencprop and OF_getprop_alloc
Change OF_getencprop_alloc semantics to be combination of malloc and
OF_getencprop and return size of the property, not number of elements
allocated.
For the use cases where number of elements is preferred introduce
OF_getencprop_alloc_multi helper function that copies semantics
of OF_getencprop_alloc prior to this change.
This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi
function signatures consistent with OF_getencprop_alloc and
OF_getencprop_alloc_multi.
Functionality-wise this patch is mostly rename of OF_getencprop_alloc
to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo
where 1 was used as a block size.

Clean up OF_getprop_alloc API
OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.
For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.

Mainly focus on files that use BSD 2-Clause license, however the tool I

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Enable using ofw_bus_find_compatible in early platform code
Before this patch function ofw_bus_find_compatible was using
memory allocations in order to find compatible node and the property's
length. This way there was always a suited buffer for property,
however this approach had also disadvantages - ofw_bus_find_compatible
couldn't be used when malloc is not available, e.g. during fdt fixup stage.
In order to remove the usage limitation of ofw_bus_find_compatible(),
this patch modifies the function to use ofw_bus_node_is_compatible()
(instead of the one without _int suffix), which uses a fixed
buffer on stack instead of dynamic allocations.

to given resource.
- At bus_setup_intr() time, mapping entry stored in resource is used
for delivery of requested interrupt configuration.
- For MSI/MSIX interrupts, mapping entry is created within
pci_alloc_msi()/pci_alloc_msix() call.
- For legacy PCI interrupts, mapping entry must be created within

Currently, there is no easy way to know in advance how many entries a list parsed by
ofw_bus_parse_xref_list_alloc() in sys/dev/ofw/ofw_bus_subr.c has.
This patch:
* teaches the existing function about handling idx == -1 and returning how big
the set is; then renames it as _internal;
* create a new function that asserts idx != -1, so the old API is maintained;
* add a new function that returns just the list length.

Open Firmware interrupt specifiers can consist of arbitrary-length byte
strings and include arbitrary information (IRQ line/domain/sense). When the
ofw_bus_map_intr() API was introduced, it assumed that, as on most systems,
these were either 1 cell, containing an interrupt line, or 2, containing
a line number plus a sense code. It turns out a non-negligible number of
ARM systems use 3 (or even 4!) cells for interrupts, so make this more
general.
Provide a simpler and more standards-compliant simplebus implementation to
get the Routerboard 800 up and running with the vendor device tree. This
does not implement some BERI-specific features (which hopefully won't be
necessary soon), so move the old code to mips/beri, with a higher attach
priority when built, until MIPS interrupt domain support is rearranged.
Allow nesting of simplebuses.

Add a set of helpers (ofw_bus_get_status() and ofw_bus_status_okay()) to
process "status" properties of OF nodes.
I've avoided adding new KOBJ methods here so that we don't have to modify
every ofw_bus in the tree. Since 100% of implementations of ofw_bus use
only ofw_bus_gen_*(), it might be worth garbage-collecting the other
methods as well.

Simplify the ofw_bus_lookup_imap() API slightly: make it allocate maskbuf
internally instead of requiring the caller to allocate it.

Configure interrupt sense based on device tree information. This extends
the OF interrupt map API to return sense information to the caller and
the PowerPC Open Firmware PCI base driver to use it to program the PIC.

Add a helper routine to search for a compat string in a table that
associates compat strings with arbitrary values that mean something to
the driver. This is handy for drivers that support several variations
of similar hardware and need to know which one matched.

Add a kernel interface (OF_xref_phandle()) for systems where phandles
used as cross-references in the device tree and phandles as used by the
Open Firmware client interface are in different namespaces. This include
IBM pSeries hardware as well as FDT systems. FDT certainly abuses
ihandles for this purpose and should be modified to use this API
eventually. This changes no behavior on systems where FreeBSD already
worked.

Prepare and extend OFW layer for FDT support.
o Let OFW_INIT() and OF_init() return status value.
o Provide helper routines for 'compatible' property handling.
o Only compile OF and OFW code, which is relevant in FDT scenario.
o Other minor cosmetics

Fix the OFW interrupt map parser to use its own idea of the number of interrupt
cells in the map, instead of using a value passed to it and then panicing if it
disagrees. This fixes interrupt map parsing for PCI bridges on some Apple
Uninorth PCI controllers.

Adapt parts of the sparc64 Open Firmware bus enumeration code (in particular,
the code for parsing interrupt maps) to PowerPC and reflect their new MI
status by moving them to the shared dev/ofw directory.
This commit also modifies the OFW PCI enumeration procedure on PowerPC to
allow the bus to find non-firmware-enumerated devices that Apple likes to add,
and adds some useful Open Firmware properties (compat and name) to the pnpinfo
string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the
change to PCI enumeration on PowerPC, X has started working again on PPC
machines with Grackle hostbridges.

- Add a new method ofw_bus_default_get_devinfo() that allows to retrieve
a newly introduced struct ofw_bus_devinfo which can hold the OFW info
of a device recallable via the ofw_bus KOBJ interface. Introduce a set
of functions ofw_bus_gen_get_*() which use ofw_bus_default_get_devinfo()
to provide generic subroutines for implementing the rest of the ofw_bus
KOBJ interface in a bus driver.
This is inspired by bus_get_resource_list() and bus_generic_rl_*_resource()
and allows to reduce code duplication in bus drivers as they only have
to provide an ofw_bus_default_get_devinfo() implementation in order to
provide the ofw_bus KOBJ interface via ofw_bus_gen_get_*().
- While here add a comment to ofw_bus_if.m describing the intention of
the ofw_bus KOBJ interface.
