zain wang ce31ddd5c4 drm/bridge: analogix_dp: Only wait for panel ACK on PSR entry ... We currently wait for the panel to mirror our intended PSR state before continuing on both PSR enter and PSR exit. This is really only important to do when we're entering PSR, since we want to be sure the last frame we pushed is being served from the panel's internal fb before shutting down the soc blocks (vop/analogix). This patch changes the behavior such that we only wait for the panel to complete the PSR transition when we're entering PSR, and to skip verification when we're exiting.
