[bhnd] Add support for querying the attachment type of the bhnd bus.
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)
