drm/msm: add support for HDR playback control sequence
HDR playback needs metadata to be sent to the sink
while the playback is ongoing and needs a proper
teardown sequence when the playback has ended with respect
to the infoframe being sent to the sink.
This needs a state machine to synchronize start/stop of
the playback with sending the right metadata along with
resetting the infoframe HDMI registers.
Add support for this HDR playback control state machine.
