Currently we are configuring Panel Replay on sink when it get's enabled. This means we need to do full modeset when enabling Panel Replay. This is required as DP specification is saying sink Panel Replay needs to be configured before link training. Avoid full modeset by enabling Panel Replay on sink always when it's supported by the sink and the source.
