Subject: [PATCH v4 10/12] arm/dts: omap4-sdp: Add twl6030, i2c3 and i2c4 devices

Update DTS file with required clock frequencies
for the i2c client devices existing on sdp4430.

Add the twl6030 node inside the i2c1 controller node.
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 the RTC submodule inside the twl node.

Add tmp105 temperature sensor in i2c3
Add bh1780 Ambient Light Sensor in i2c3
Add hmc5843 3-Axis Digital Compass in i2c4
