[PATCH 00/15][OEM-5.10] UBUNTU: SAUCE: add support of MSO panel

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1921318

[Impact]
New panel with MSO feature can't be light up.

[Fix]
This series enables eDP MSO on TGL+.
Patch set:
https://patchwork.freedesktop.org/series/86992/
https://patchwork.freedesktop.org/series/87536/
It depends on another patch set:
https://patchwork.freedesktop.org/series/83780/

[Test Case]
Verified on the target platform and other 2 laptops without MSO feature,
internal display good;
external monitor good;
external monitor good via dock;
no errors after GPU benchmark;

[Where problems could occur]
Intel GPU may lose the output.
Due to the concern of the big change, target to oem-5.10 only.
