It is not safe to unbind and then rebind a subdevice in the rcar-vin pipeline. Depending on what subdevice and in what order a device is rebound the rcar-vin driver can misbehave. Until this can be solved suppress the files in sysfs which allows for this. This is in line with what is done for other subdevices exclusively use with the rcar-vin pipeline, e.g. rcar-csi2.
