pc, pc64: add minimal HPET driver to measure LAPIC and TSC frequencies
This adds the new function pointer PCArch.clockinit(),
which is a timer dependent initialization routine.
It also takes over the job of guesscpuhz(). This way, the
architecture ident code can switch between different
timers (i8253, HPET and XEN timer).
