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

Merge a PM QoS fix and a hibernation fix for 6.5-rc2.

 - Unbreak the /sys/power/resume interface after recent changes (Azat
   Khuzhin).

 - Allow PM_QOS_DEFAULT_VALUE to be used with frequency QoS (Chungkai
   Yang).

* pm-sleep:
  PM: hibernate: Fix writing maj:min to /sys/power/resume

* pm-qos:
  PM: QoS: Restore support for default value on frequency QoS
