[PATCH v9 10/28] rcar-vin: do not reset crop and compose when setting format

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

It was a bad idea to reset the crop and compose settings when a new
format is set. This would overwrite any crop/compose set by s_select and
cause unexpected behaviors, remove it. Also fold the reset helper in to
the only remaining caller.
