Add support for the rk805 regulator. The regulator module consists
of 4 DCDCs, 3 LDOs.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

Add support for the rk805 regulator. The regulator module consists
of 4 DCDCs, 3 LDOs.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

The RK805 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clocking
Both RK808 and RK805 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

Following regulators of the RK808 PMIC block are supported. Note that
the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
number as described in RK808 datasheet.
