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.

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:
