[patch 03/38] x86/apm: Remove last LATCH usage

LATCH is a historical leftover and has been replaced with PIT_LATCH in all
other places a decade ago. Replace the last holdout and remove the
definition from jiffies.h.

This allows to remove the otherwise unused CLOCK_TICK_RATE define in the
next step.
