Bug description:
[Impact]
There was randomly graphic glitch on edp with AMDGPU

[Fix]
AMD provides a patch to disable PSR on this panel to fix the issue.
The patch is under AMD internal review and is not submitted to upstream yet.
c31b41f1cb32 drm/amd/display: Disable PSR-SU on some OLED panel

[Test]
1. Boot in OS
2. Idel the machine for a while (~1 min) and move the cursor.
3. There should not have any graphic glitch when using the machine.

[Where problems could occur]
This is a quirk for a specific panel, so should be pretty safe.
