[SRU v2] [J/OEM-5.14] [PATCH 00/11] Fix screen flickering caused by PSR on Intel TGL platform

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1978252

[Impact]
Screen flickers on certain Intel TGL laptops.

[Fix]
Enable PSR2 selective fetch along with several PSR fixes.

[Test]
Screen flickers can no longer be observed on affected laptops.

[Where problems could occur]
PSR can be glitchy. Fortunately it's not system breaking so we can push
subsequent fixes if needed.

v2:
Explain the change in patch 04/11.
