[media] rcar_vin: Remove obsolete platform data support
Since commit 3d7608e4c169af03 ("ARM: shmobile: bockw: remove legacy board file and config"), Renesas R-Car SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to use platform data anymore, hence remove platform data configuration.
