For arch specific codes, we use arch_xxx() to name the function.
So, rename cpu_ticks/cpu_tickrate/set_hw_timeout/init_hw_timer
to follow this convention. Then, use arch interface to set timeout
value in update_physical_timer().
Furthermore, remove hw_timer.h and move its contents into common/
timer.h.

Replace rdstc() and get_tsc_khz() with their architectural agnostic
counterparts cpu_ticks() and cpu_tickrate().

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.
