media: rcar-vin: move media bus configuration to struct rvin_dev

Bus configuration will once the driver is extended to support Gen3
contain information not specific to only the directly connected parallel
subdevice. Move it to struct rvin_dev to show it's not always coupled
to the parallel subdevice.
