The vc4 HDMI connector reset implementation creates a pristine state, initializes the HDMI state, and sets the TV margins. It does not perform any hardware reset.
Since this is equivalent to what atomic_create_state expects, convert the reset function to an atomic_create_state hook that returns the initialized state.
