Subject: [PATCH 03/17] ARM: dts: r8a7742: Add I2C and IIC support

Add the I2C[0-3] and IIC[0-3] devices nodes to the R8A7742 device tree.

Automatic transmission for PMIC control is not available on IIC3 hence
compatible string "renesas,rcar-gen2-iic" and "renesas,rmobile-iic" is
not added to iic3 node.
