[PATCH] ARM: dts: marzen: Enable I2C support

[Geert Uytterhoeven]

Enable the single I2C bus available on the Marzen development board.
As this bus contains an AK4643 codec, it must be limited to 100 kHz.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

To be queued in renesas-devel-for-v6.4.
