ANDROID: power: wakeup_reason: wake reason enhancements

Browse Source 
These changes build upon the existing Android kernel wakeup reason code
to:
* improve the positioning of suspend abort logging calls in suspend flow
* add logging of abnormal wakeup reasons like unexpected HW IRQs and
  IRQs configured as both wake-enabled and no-suspend
* add support for capturing deferred-processing threaded nested IRQs as
  wakeup reasons rather than their synchronously-processed parents
