drm/amdgpu/display - only update eDP's backlight level when necessary
[Why]
The original logic is to update eDP's backlight level
on every amdgpu dm atomic commit, which causes excessive
DMUB write. As a result, when playing game or moving window
around, DMUB timeout and system lagging are observed.
[How]
We only need to update eDP's backlight level when current level
doesn't match requested level.
