[PATCH v4 4/4] rcar-vin: Always setup controls when opening video device

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

Now that both Gen2 (video device centric) and Gen3 (media device
centric) modes of the driver have controls it is required to always
setup the controls when opening the devices. Remove the check which only
calls v4l2_ctrl_handler_setup() for Gen2 and call it unconditionally.
