[RFC][PATCH 4/4] OMAP4: PMIC: Update TWL mfd driver to create twl6030 regulators

[balajitk]

From: Rajendra Nayak <rnayak@xxxxxx>

This patch adds initial support for creating twl6030 PMIC
specific voltage regulators in the twl mfd driver.

Board specific regulator configurations will have to be passed from
respective board files.
