drm/amd/display: Restore backlight brightness after system resume
Laptops with AMD APU doesn't restore display backlight brightness after
system resume.
This issue started when DC was introduced.
Let's use BL_CORE_SUSPENDRESUME so the backlight core calls
update_status callback after system resume to restore the backlight
level.
Tested on Dell Inspiron 3180 (Stoney Ridge) and Dell Latitude 5495
(Raven Ridge).
