Interestingly enough, ppc32 had broken timekeeping for ages...  It
worked, but probably drifted a bit more than could be explained by the
actual bad precision of the timebase calibration.  We discovered that
recently when somebody figured out that the common code was using
CLOCK_TICK_RATE to correct the timekeeing, and ppc32 had a completely
bogus value for it.

This patch turns it into something saner.  Probably not as good as doing
something based on the actual timebase frequency precision but I'll
leave that sort of math to others.  This at least makes it better for
the common HZ values.

Merge a few asm-ppc and asm-ppc64 header files.
Note: the merge of setup.h intentionally does not carry
forward the m68k cruft.  That means this patch continues
to break the already broken amiga on the ppc32.

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!
