NOTE: This currently will use I2C1 bus communication path to set the voltage in device tree boot. In the legacy non device tree boot, we continue to use twl-common.c which bypasses I2C1 bus communication path and uses I2C4 bus path using OMAP voltage libraries. We should eventually be able to use I2C4 path once we have voltage regulator for OMAP which is capable of using the voltage controller/voltage processor IP blocks.
