[aon_timer] Change escalate_en control to cpu_en

* The issue with using escalate_en is that if the software configures
  the alert handling to skip from normal directly to scrap, we may not
  halt the watchdog timer.  There are also similar issues with other
  invalid states.

* By using cpu_en, we align the behavior of the aon_timer with that of
  the processing element (its main consumer) and thus is more consistent
  overall.  If the cpu is running, then the watchdog / wake timer should
  be in effect.  If the cpu is halted due to life cycle reasons, there
  would be no one to consume the output anyways.
