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.
