[SRU] [OEM-5.14] [PATCH 00/12] Additional fix for TGL + AUO panel flickering

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1983297

[Impact]
"UBUNTU: SAUCE: drm/i915/display/psr: Fix flicker on TGL + AUO panel"
alone used to fix the issue on the AUO panel. But the panel starts to
flicker like crazy on top of the new stable commits.

[Fix]
Backport full fix for PSR2 selective fetch, but only enable it on TGL +
specific AUO panel. The last three patches which enable PSR2 on ADL-P
are dropped.

[Test]
Originally the backport regressed ADL + BOE panel, so this time we
put extra effort to ensure those system are unaffected, while TGL + AUO
panel is still fixed.

[Where problems could occur]
Most code changes only have functional impact when PSR2 selective fetch
is enabled. Some of changes are under more general call path for
hardware cursor rendering.
