drm/amd/display: Remove power sequencing check 

[ Upstream commit b0399e22ada096435de3e3e73899aa8bc026820d ]

[Why]
	Some ASICs keep backlight powered on after dpms off
	command has been issued.

[How]
	The check for no edp power sequencing was never going to pass.
	The value is never changed from what it is set by design.
