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.
