Changes:
- Fixed incorrect MIPS74k vendor ID in the bhnd core descriptor tables
- Fixed MIPS core driver's matching against MIPS/MIPS33 cores.
- Improved MIPS3302 core description.
- Enabled BUS_PASS_BUS on the bhnd nexus drivers to allow early probing
of the MIPS core.
- Enabled BUS_PASS_CPU on the MIPS core driver to ensure correct attach
order.
- Disabled matching of the MIPS core driver on non-SoC devices.

Now that bhnd(4) provides feature parity with the previous siba/mips
implementation, we can switch sentry5 over and begin lifting common
support code out for use across bhnd(4) embedded targets.
Changes:
- Fixed enumeration of siba(4) per-core address maps, required for
discovery of memory mapped chipc flash region on siba(4) devices.
- Simplified bhnd kernel configuration (dropped 'bhndbus' option).
- Replaced files.broadcom's direct file references with their
corresponding standard kernel options.
- Lifted out common bcma/siba nexus support, inheriting from the new
generic bhnd_nexus driver.
- Dropped now-unused sentry5 siba code.
- Re-integrated BCM into the universe build now that it actually compiles.

This adds a BHND_BUS_GET_ATTACH_TYPE(); the primary use-case is to let
chipc make a coarse-grained determination as to whether UART, SPI, etc
drivers ought to be attached, and on fullmac devices, whether a real
CPU driver ought to be skipped for the ARM core, etc.
Tested:
* BCM4331 (BHND)
* BCM4312 (SIBA)

This patch introduces support of BHND on SoC: nexus-to-bhnd drivers.
bhnd_soc is attached under nexus and responsible for all BHND-style calls
from bhnd(4) bus to parents.
bcma_nexus is bhnd(4) bus, attached to bhnd_soc and implement all
nexus-style behaviour of BHND.

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

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!
