drm/amd/display: Reset apply_eamless_boot_optimization when dpms_off

Browse Source 
[ Upstream commit ad335b5fc9 ]

[WHY&HOW]
The user closed the lid while the system was powering on and opened it
again before the “apply_seamless_boot_optimization” was set to false,
resulting in the eDP remaining blank.
Reset the “apply_seamless_boot_optimization” to false when dpms off.
