pinctrl: sh-pfc: Reduce kernel size for narrow VIN channels
Some VIN channels support less than 24 lanes. As union vin_data always
consumes space for 24 lanes, this wastes memory.
Hence introduce new smaller unions vin_data12 and vin_data16, to
accommodate VIN channels with only 12 or 16 lanes.
This reduces the static pin controller driver size by 320 bytes for
R-Car V2H, and by 96 bytes for R-Car E2.
