drm/amd/display: Restore correct backlight brightness after a GPU reset
[Why]
GPU reset will attempt to restore cached state, but brightness doesn't
get restored. It will come back at 100% brightness, but userspace thinks
it's the previous value.
[How]
When running resume sequence if GPU is in reset restore brightness
to previous value.
