Merge branches 'pm-core', 'pm-sleep' and 'pm-qos' 

* pm-core:
  PM-runtime: Call pm_runtime_active|suspended_time() from sysfs
  PM-runtime: Consolidate code to get active/suspended time

* pm-sleep:
  PM / wakeup: Drop wakeup_source_drop()
  PM / wakeup: Rework wakeup source timer cancellation

* pm-qos:
  PM / QoS: Fix typo in file description
