OMAP3: PM: Register TWL4030 pmic info with the voltage driver.

This patch registers the TWL4030 PMIC specific informtion
with the voltage driver. Failing this patch the voltage driver
is unware of the formula to use for vsel to voltage and vice versa
conversion and lot of other PMIC dependent parameters.

This file is based on the arch/arm/plat-omap opp_twl_tpl.c file
by Paul Walmsley. The original file is replaced by this file.
