media: rcar-vin: extend {start, stop}_streaming to work with media controller

Browse source

The procedure to start or stop streaming using the non-MC single
subdevice and the MC graph and multiple subdevices are quite different.
Create a new function to abstract which method is used based on which
mode the driver is running in and add logic to start the MC graph.
