Bug description:
[Impact]
On some PSR2 supported panels, which connects to Intel Graphics has flicker
symptom. It gets normal after booting the kernel with parameter `i915.
enable_psr=0`
[Fix]
Backport one patch from upstream.
https://cgit.freedesktop.org/drm-tip/commit/drivers/gpu/drm/i915/display/intel_psr.c?id=084aab04cc60e5eab32287d0483c33e12c92da87
[Test]
Booting the patched kernel with problematic panel (LGD LCD_VD78M), check if
the display has abnormal flickering problem on graphics interfaces.
[Where problems could occur]
The risk of regression is low. It only fixes problem on panels which support
PSR2.
