This patch add support for the bcma bus. Broadcom uses only Mips 74K
CPUs on the new SoC and on the old ons using ssb bus there are no Mips
74K CPUs.

I'm not involved in development for embedded devices but I believe
that space is quite important for them.

You force compiling both: ssb and bcma for every device using bcm47xx.
I think ppl may want to compile only one bus driver.

Yes that has to be improved as there should also be an option to use the
compiler optimazions for the new MIPS 74K CPU core.
