[PATCH] i2c: rcar: Remove obsolete platform data support

[Geert Uytterhoeven <geert+renesas@glider.be>]

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.

Commit 4baadb9e05c68962 is now in arm-soc/for-next.
