Tom Chung 4f26c95ffc drm/amd/display: Fix brightness level not retained over reboot ...

[Why]
During boot up and resume the DC layer will reset the panel
brightness to fix a flicker issue.

It will cause the dm->actual_brightness is not the current panel
brightness level. (the dm->brightness is the correct panel level)

[How]
Set the backlight level after do the set mode.
