[PATCH] ARM: shmobile: henninger: add I2C2 DT support

[Sergei Shtylyov]

Define the Henninger board dependent part of the I2C2 device node.
Add device nodes for Analog Devices ADV7180 video decoder and Renesas EEPROM
connected to this I2C bus.

Based on the Koelsch I2C2 device tree patch by Wolfram Sang.
