Support voltage control for regulators on ROHM BD71815 PMIC.
ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.
LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.
This work is derived from driver originally written by Tony Luo
<luofc@embedinfo.com> - although not much of original work is left.
