Bug Description
[Impact]
On AMD RENOIR gpu, after S3 backlight brightness can not be changed.
[Fix]
Pevious patch prevent loading iram, then dmcu can not work.
Remove unused check to load iram right. Then backlight works well.
[Test]
Verified on hardware, after 10 times of S3, backlight can be changed by
hotkey.
[Regression Potential]
Low
Upstream fix, backports is minimal.
RENOIR is only supported on oem-5.6, no focal patch.
