bhnd(4): implement MIPS and PCI(e) interrupt support

On BHND MIPS SoCs, this replaces the use of hard-coded MIPS IRQ#s in the
common bhnd(4) core drivers; we now register an INTRNG child PIC that
handles routing of backplane interrupt vectors via the MIPS core.

On BHND PCI devices, backplane interrupt vectors are now routed to the
PCI/PCIe host bridge core when bus_setup_intr() is called, where they are
dispatched by the PCI core via a host interrupt (e.g. INTx/MSI).

The bhndb(4) bridge driver tracks registered interrupt handlers for the
bridged bhnd(4) devices and manages backplane interrupt routing, while
delegating actual bus interrupt setup/teardown to the parent bus on behalf
of the bridged cores.

bhndb(4): Skip disabled cores when performing bridge configuration probing.

On BCM4321 chipsets, both PCI and PCIe cores are included, with one of
the cores potentially left floating.

Since the PCI core appears first in the device table, and the PCI
profiles appear first in the resource configuration tables, this resulted in
incorrectly matching and using the PCI/v1 resource configuration on PCIe
devices, rather than the correct PCIe/v1 profile.

Migrate bhndb(4) to the new bhnd_erom API.

Adds support for probing and initializing bhndb(4) bridge state using
the bhnd_erom API, ensuring that full bridge configuration is available
*prior* to actually attaching and enumerating the bhnd(4) child device,
allowing us to safely allocate bus-level agent/device resources during
bhnd(4) bus enumeration.

- Add a bhnd_erom_probe() method usable by bhndb(4). This is an analogue
to the existing bhnd_erom_probe_static() method, and allows the bhndb
bridge to discover the best available erom parser class prior to newbus
probing of its children.
- Add support for supplying identification hints when probing erom
devices. This is required on early EXTIF-only chipsets, where chip
identification registers are not available.
- Migrate bhndb over to the new bhnd_erom API, using bhnd_core_info
records rather than bridged bhnd(4) device_t references to determine
the bridged chipsets' capability/bridge configuration.
- The bhndb parent (e.g. if_bwn) is now required to supply a hardware
priority table to the bridge. The default table is currently sufficient
for our supported devices.
- Drop the two-pass attach approach we used for compatibility with bhndb(4) in
the bhnd(4) bus drivers, and instead perform bus enumeration immediately,
and allocate bridged per-child bus-level resources during that enumeration.

[bhnd] Centralize fetching of board information

Centralizes fetching of board information (vendor, type, revision, etc),
and adds support for matching quirks against board identification info.

* Adds a BHND_BUS_READ_BOARD_INFO(), allowing bhnd bus/bus parent(s) to
handle implementation-specific fetching of board info.
* Integrates board type constants from the latest Broadcom ISC-licensed
bcmdevs.h included in dd-wrt's Broadcom driver source drops.
* Adds support for matching on chip/board quirks to bhnd_device_quirks()/
bhnd_chip_quirks().
* Use the new board/chip quirk matching to match Apple devices that failed
to set BFL2_PCIEWAR_OVR in SROM.

Bring over the initial rewrite of the broadcom bus support found in their
SoCs and various chips (including, famously, their wifi chips.)

This is "just" (all 20,000 lines of it) code to enumerate the various
versions of busses inside these devices, including the PCI bridge and
the direct SIBA bridge found in MIPS chips.

It also includes shared code for some bus operations (suspend, resume, etc);
EEPROM/SROM/etc parsing and other things that are shared between chips.

Eventually this'll replace the code that bwi/bwn uses for the internal
bus, as well as some apparently upcoming mips74k broadcom SoC support
which uses bwn!

Thanks to Landon Fuller <landonf@landonf.org> for all this work!
