v2 cover ARM: OMAP4: register V1V8, V2V1 regulators

Hello,

Changes since v1:
- rebased on 3.4-rc6

Original intro message:

This series adds common configuration for the V1V8, V2V1 regulators from twl6030. These regulators are commonly used to feed the twl6040 audio IC on OMAP4 based boards (SDP4430, PandaBoards).

The regulator support for the twl6040 MFD driver will be going via MFD tree to avoid cross tree issues.

Regards,
Peter

PATCH v2 1/3 OMAP4: twl-common: Add twl6030 V1V8, V2V1 SMPS common configuration

V1V8 supply from twl6030 commonly used as VIO for the machine. V2V1 is adviced to supply the twl6040, and also to feed the twl6030's VCXIO_IN, and VDAC_IN inputs.
Create the common regulator configurations for these regulators:
Make the V2V1 as supply_regulator for VCXIO, VDAC.
Add twl6040 (1-004b) as consumer for V1V8, and V2V1.
