From: Rajendra Nayak <rnayak@xxxxxx>
This version of patch series enables RUN TIME selection of TWL4030 or TWL6030.
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.
