The Raspberry Pi firmware driver has no compile dependencies on the
BCM2835 mailbox driver. It's just a indirect runtime dependency: the
driver only works on a Raspberry Pi.
Change the dependency from BCM2835_MBOX to ARCH_BCM2835. Also allow
compile tests. This allows drivers that have build time dependencies
on this firmware driver to be compile tested as well.

This option enables support for communicating with the firmware on the
Raspberry Pi.

No objection, however I think this should also have:
default ARCH_BRCM2835
because without the firmware driver there is effectively nothing that
works. See this patch series:
