[media] media i.MX27 camera: add start_stream and stop_stream callbacks

Browse source

Add "start_stream" and "stop_stream" callback in order to enable
and disable the eMMa-PrP properly and save CPU usage avoiding
IRQs when the device is not streaming. This also makes the driver
return 0 as the sequence number of the first frame.
