a73ac06d93 [bhnd] Add bhnd_resource support for the bus_(read|write)(_multi_)stream_* functions.
This adds additional bhnd_resource shims used by the upcoming SPROM deltas.

d935257080 [bhnd] Replace is_hostb_device() with a more general find_hostb_device()
This allows bus children to query for the host bridge device, rather
than having to iterate over all attached devices.

386fb140a6 [bhnd] Clean up bhnd resource handling and inherited bus methods
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().

4ad7e9b01a 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!
