drm/amd/display: To update backlight restore mechanism

Browse source

[Why]
Cached backlight is never being updated since panel_cntl specific
registers were moved from abm to panel_cntl.

[How]
Update cached backlight in set_abm_immediate_disable as what we used to
do. Also, update the priority of backlight restore mechanism so that
cached backlight has the highest priority since it is always correct.
