The SoC does actually have two types of serial port; a PL011 which we're
using as the primary UART, and a 16C650-alike port. There's no PL010
present. I'll strip this down to just PL011 support since that's all
that's in use right now.

This was originally named bcm2708.c downstream, but I renamed it to
common.c following the example of mach-picoxcell and mach-zynq, which
IIRC you had pointed out as exemplary platforms. Still, I can rename it
back if you want.

OK. It's required right now though. I assume we should aim to check this
in for 3.7. Should I rebase this patch on top of whatever change removes
the need for timex.h? Such a patch doesn't appear to be in linux-next
right now though.
