  Add support for event timers whose clock frequency can change while running.

  Apparently all ARM configs build kern_et.c, but only a few of them also
  build kern_clocksource.c, un-break the build by not referencing functions in
  kern_clocksource if NO_EVENTTIMERS is defined.

  Add variable-frequency support to the arm mpcore eventtimer driver.

  mpcore_timer: Disable the timer and clear any pending bit, then setup the
  new counter register values, then restart the timer.  Also re-nest the parens
  properly for casting the result of converting time and frequency to a count.
