f7e9e9feb0 drm/amdgpu: Remove checking for atombios 
This is a left over from radeon, amdgpu doesn't support any
non-atombios parts and amdgpu_device_init would bail if the
check for atombios failed anyway.

74b3112e95 drm/amdgpu: Restore LCD backlight level on resume 
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)
