drm/msm/mdp5: add skeletal mdp5_state
Add basic state duplication/apply mechanism. Following commits will
move actual global hw state into this.
The state_lock allows multiple concurrent updates to proceed as long as
they don't both try to alter global state. The ww_mutex mechanism will
trigger backoff in case of deadlock between multiple threads trying to
update state.
