arm/dts: omap4-panda: Add twl6030 and i2c EEPROM
Update pandaboard dts file with required clock frequencies for the i2c client devices existing on pandaboard. Add the twl6030 node in i2c1 controller. This is the minimal support needed to boot OMAP4 boards without any crash. The support for all the features included in this MFD will be added later. Add a generic i2c EEPROM entry.
