drm/amdgpu: Restore LCD backlight level on resume
commit 74b3112e95073b351e3b0b9799795bc76f8415fa upstream.
Instead of only enabling the backlight (which seems to set it to max
brightness), just re-set the current backlight level, which also takes
care of enabling the backlight if necessary.
Port of radeon commit:
drm/radeon: Restore LCD backlight level on resume (>= R5xx)
