NVRAM, ChipCommon, etc).
This extends the existing handling of NVRAM core discovery to support
locating additional devices that may be attached either directly as real
cores, or indirectly via ChipCommon (e.g. bhnd_pmu).
When attached as a SoC root bus (as opposed to a bridged WiFi device),
the platform devices may not be attached until later bus passes,
necessitating delayed discovery/initialization.

pci_if.
This allows bhnd(4) to manage per-device state (such as per-core
pmu/clock refcounting) on behalf of subclass driver instances.

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!
