OMAP4: Add DT support for i2c and twl6030

Hi Tony and Rob,

Here is the updated version of the i2c + twl DT adaptation series.

This update, compared to v2 [1], is adding some dedicated dtsi files for the twl PMIC and audio IC. These devices will contain a huge amount of regulator nodes and thus deserve a dedicated file to avoid every boards to redefine the same data.
The twl patch is now included in Samuel's for-next branch and thus dropped from this update.
The i2c binding was cleaned as suggested by Rob to avoid all the ugly hexa flags inside the DTS.

The pm.c was updated to prevent the SR / VP initialization in the DT context since none of them is DT aware for the moment.

A couple of basic i2c devices are added for panda, beagle and sdp board.

Patches are based on for_3.3/2_dt_irq, to get the latest GIC binding, and are available here:
git://gitorious.org/omap-pm/linux.git for_3.3/3_omap_dt_i2c_twl

Tested on Beagle and sdp4430.

Comments are welcome.

Regards,
Benoit
