Subject: [PATCH 00/10] Add APSS RSC to Cluster power domain

This series patches 1 to 4 adds/corrects the cpuidle states/
apps_rsc TCS configuration to make it same as downstream kernel.

The patches 5, 6 and 7 adds apps_rsc device to cluster power domain such
that when cluster is going to power down the cluster pre off notification
will program the 'sleep' and 'wake' votes in SLEEP TCS and WAKE TCSes.

The patches 8, 9 and 10 are to program the next wakeup in CONTROL_TCS.

[1], [2] was older way of programming CONTROL_TCS (exporting an API and
calling when last CPU was entering deeper low power mode). Now with patch
number 5,6 and 7 the apps RSC is added to to cluster power domain and hence
these patches are no longer needed with this series.

The series is tested on SM8250 with latest linux-next tag next-20220107.
