x86: Geode Multi-Function General Purpose Timers support

This adds support for Multi-Function General Purpose Timers.  It detects the
available timers during southbridge init, and provides an API for allocating
and setting the timers.  They're higher resolution than the standard PIT, so
the MFGPTs come in handy for quite a few things.

Note that we never clobber the timers that the BIOS might have opted to use;
we just check for unused timers.
