Adds support for RTCs (through genrtc) for M68KNOMMU.
Board-specific code will have to link the appropriate RTC driver to the
mach_hwclk callback, at minimum.
This patch switches the 68360 code over to using rtc_time.

The 523x timer TRR register is a full 32bits, the older register (on
other ColdFire parts) was only 16 bits. Use the right type of
__raw_read when accessing it.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
