[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)

[bhnd] Initial bhnd(4) SPROM/NVRAM support.
This adds support for the NVRAM handling and the basic SPROM hardware used on siba(4) and bcma(4) devices, including:
* SPROM directly attached to the PCI core, accessible via PCI configuration space. * SPROM attached to later ChipCommon cores. * SPROM variables vended from the parent SoC bus (e.g. via a directly-attached flash device).
Additional improvements to the NVRAM/SPROM interface will be required, but this changeset stands alone as working checkpoint.
