skylake: allow timer_monotonic_get() in all stages
The timer_monotonic_get() function wasn't being compiled for
romstage. To simplify the implementation don't keep track of
partial microsecond ticks and just return the MSR value divided
by 24 (24MHz clock).
BUG=chrome-os-partner:42115
BRANCH=None
TEST=Build and booted glados. Used monotonic timers in romstage
in subsequent patches.
