drm/amd/display: Cache backlight_millinits in link structure and setting brightness accordingly
[Why]
Need to save the cached backlight level so that display lights up using
appropriate brightness level instead of the default brightness when
waking up from s0i3.
[How]
Adding a backlight level cache in link structure. Also instead on
calling set_default_brightness_aux, check if cached values exists.
