[PATCH 10/11] media: rcar-vin: split rvin_s_fmt_vid_cap()

["Niklas Söderlund" <niklas.soderlund+renesas@ragnatech.se>]

To support unbind and rebinding of subdevices rvin_s_fmt_vid_cap() needs
to be called from with in the driver itself. Rename the function
__rvin_s_fmt_vid_cap() and create a wrapper which can be used by
vidioc_s_fmt_vid_cap.
