hv/mod_timer: split tsc handling code from timer.

Browse Source 
Generalize and split basic cpu cycle/tick routines from x86/timer:
- Instead of rdstc(), use cpu_ticks() in generic code.
- Instead of get_tsc_khz(), use cpu_tickrate() in generic code.
- Include "common/ticks.h" instead of "x86/timer.h" in generic code.
- CYCLES_PER_MS is renamed to TICKS_PER_MS.

The x86 specific API rdstc() and get_tsc_khz(), as well as TSC_PER_MS
are still available in arch/x86/tsc.h but only for x86 specific usage.
