[SRU] [K/L/Unstable/OEM-6.1] [PATCH 0/1] Fix SHP 5457 panel flicker when PSR2 sel fetch is enabled

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/2007516

[Impact]
Panel SHP 5457 which can be found on XPS 9320 flickers when PSR2 sel
fetch is enabled.

[Fix]
Disable PSR2 sel fetch as temporary workaround.

[Test]
PSR1 is enabled instead of PSR2. No more flicker can be observed.

[Where problems could occur]
PSR is capricious, maybe PSR1 isn't enough for some unknown corner case.
