4e87173eac x86: split get_cycles_sync
This patch splits get_cycles_sync() into  __get_cycles_sync(),
and the rdtscll part. Paravirt guests cannot issue rdtscl directly,
as it involves a function call in vdso area.

So, using the __get_cycles_sync() base, we introduce vget_cycles_sync,
which then calls the native version of rdtscll. Ideally, however, a guest
should define its own clocksource, together with a vread function

while at it.

d371698efd x86_64: Consolidate tsc calibration
Move the TSC calibration code to tsc.c. Reimplement it so the
pm timer can be used as a reference as well.
