timestamps: Switch from tsc_t to uint64_t

Cherry-pick from chromium and adjusted for added boards
and changed directory layout for arch/arm.

Timestamp implementation for ARMv7

Abstract the use of rdtsc() and make the timestamps
uint64_t in the generic code.

The ARM implementation uses the monotonic timer.
