EDP1.5 specification says:

"Although defined for the PR function in DP Standard, the
ASYNC_VIDEO_TIMING_NOT_SUPPORTED_IN_PR and DSC_DECODE_NOT_SUPPORTED_IN_PR
bits (DPCD 000B1h[3, 2], respectively) are DP-specific and are therefore
not used in eDP."

Stop using SYNC_VIDEO_TIMING_NOT_SUPPORTED_IN_PR on eDP.
