Disable the i915.psr2 on AUO(0x06,0xaf,0xa3,0xc3) panel

[AceLan Kao]

[Impact]
In Dell oem project, we found the graphic is flickering on some
machines, finally we narrowed down the issue on (some specific panels +
i915.psr2 enabled), and the issue was reported to Intel, Intel fixed
the issue in the most recent mainline kernel.

It is hard to backport the patches to oem-6.5, so we wrote
a workaround patch to disable the psr2 for those pannels in the oem-6.5.

[Fix]
A quirk to disable psr2 on the AUO panel.

The real fix has been merged into noble and 6.8-oem kernels.

[Test]
1. boot up and moving the cursor around every cornors of the screen
2. it should shows the graphics well and no flicks

[Where problems could occur]
The quirk only affects the listed panel, so there should be no impact on other panels.
And disable psr2 never introduce regressions, just impact run time power consumption a little bit.
