[PATCH v3 00/20] Panel replay selective update support

[Jouni Högander]

This patch set is implementing panel replay selective update support
for Intel hardware.

It is also fixing several exisiting issues in current panel replay implementation:

ALPM status is checked even on DP (non eDP)
PSR capability change is checked even when using panel replay
Several needed functions are not execute for panel replay
Ensure link training follows enabling panel replay on sink side
Do not update phy power state for panel replay.
Do not apply workarounds not applicable for panel replay
Do not write registers/bits not applicable for panel replay
Do not disable panel replay by default

v3:
  - set has_psr for panel replay as well
  - enable sink before link training
  - do not apply all PSR workarounds for panel replay
  - do not write/read registers/bits not applicable for panel replay
  - 
v2:
  - Make psr pause/resume to work for panel replay as well
