Bug Description

[Impact]
Screen flickers on certain Intel TGL laptops + AUO panel.

[Fix]
Enable PSR2 selective fetch only for the specific case to minimize the
regression risk.

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

[Where problems could occur]
The fix becomes very specific, so any other combination won't be affected at
all.
