[PATCH 09/13] arm/dts: omap4-sdp: Add twl6030 node

[Benoit Cousson]

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

This is just 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.
