Now that we've got access to SPROM and can access board identification,
this implements all known remaining hardware work-arounds for the bhnd(4)
PCI and PCIe-G1 cores operating endpoint mode.
Additionally, this adds an initial set of skeleton PCIe-G2 hostb and pcib
drivers, required by fullmac and newer softmac devices.

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.

This is used by the upcoming SPROM code to match on chipsets
that require special handling of muxed SPROM pins.

This allows bus children to query for the host bridge device, rather
than having to iterate over all attached devices.

"make tinderbox" fails on sparc64 GENERIC-NODEBUG with:
bhnd_subr.c:188: warning: control reaches end of non-void function

This add a bhnd device table mechanism that standardizes matching of
devices on the bhnd(4) bus, discovery of device quirk flags, and should
be pluggable into the new PNPINFO machinery.

To facilitate use by SoC implementors working with bhnd-inheriting fdt/nexus
drivers:
* Splits bhnd_bus method implementations into generic bus implementations
(bhnd_bus_generic) and generic bhnd(4) driver implementations (bhnd_generic)
* Simplifies bhnd resource handling, allowing bhnd bus implementations to
support bhnd resource activation by implementing the standard BUS_*
resource APIs and BHND_BUS_ACTIVATE_RESOURCE().

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!
