regulator: rk808: Add regulator driver for RK818
Add support for the rk818 regulator. The regulator module consists of 4 DCDCs, 9 LDOs, 1 switch and 1 BOOST converter which is used to power OTG and HDMI5V. The output voltages are configurable and are meant to supply power to the main processor and other components.
