drm/amd/display: Add condition to sync eDP SW status and HW status

Browse source

[Why]
Need to disable EDP backlight when enter S4 with EDP only
and resume from S4 with secondary only.

[How]
Align the real hw and sw state via vBios scratch register in
function enable_accelerated_mode when resume from S4.
