   8 Restore power button functionality after resume operation

  10 Per Werner's suggestion, run the PMU interrupt handler immediately after resume
  11 to clear/handle any pending interrupts from that device.  This appears to
  12 resolve the  dead-powerbutton-after-resume problem.  This is not well-tested;
  13 need feedback to see if there are any side-effects or other problems.
