msm: mdss: reset ctl interface during video stop
Interface ctl needs to be reset by software during video stop to
prevent hardware's state machine from going into bad state. One
usecase that causes this to happen is when HDMI interface is
disconnected during video playback and reconnected with left and right
mixers swapped for the 3D muxing.
