adrian 240c5e5159 [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().
