Some QHD panels fail to refresh when PSR2 enabled

[Chris Chiu]

[Impact]
Some QHD (2560x1440) panels which support PSR2 refresh the display abnormally. The display frequently stop responding for few seconds on all user interactions, ex. mouse movement, TTY and any APP GUI. There's no problem on the external monitor. After disabling PSR, the problem will be gone.

[Fix]
Intel release a fix to calculate the wake up line count and configure them into PSR2_CTL accordingly.

[Test]
Verified on the problematic panels to check if the display responds smoothly to mouse movement.

[Where problems could occur]
Only affects the panels on some particular panels which supports PSR2
