drm/msm/mdp5: Add START signal to kick off certain pipelines

Browse source

Some interfaces (WB, DSI Command Mode) need to be kicked off
through a START Signal. This signal needs to be sent at the right
time and requests in some cases to keep track of the pipeline
status (eg: whether pipeline registers are flushed AND output WB
buffers are ready, in case of WB interface).
