i2c: rcar: Remove obsolete platform data support
Since commit 4baadb9e05c68962 ("ARM: shmobile: r8a7778: remove obsolete setup code"), 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. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> [wsa: removed now unused ret value and cast to proper enum type] Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
