The rk809 and rk817 are a Power Management IC (PMIC) for multimedia
and handheld devices. It contains the following components:
- Regulators
- RTC
- Clocking
Both RK809 and RK817 chips are using a similar register map,
so we can reuse the RTC and Clocking and regulators functionality.

This driver provides common support for accessing the device
through I2C interface. The device supports multiple sub-devices
including interrupts, RTC, LDO & DCDC regulators, and onkey.

Add support for the rk809 and rk817 regulator driver.
Their specifications are as follows：
1、The RK809 and RK809 consist of 5 DCDCs, 9 LDOs
and have the same registers for these components except dcdc5.
2、The dcdc5 is a boost dcdc for RK817 and is a buck for RK809.
3、The RK817 has one switch but The Rk809 has two.
The output voltages are configurable and are meant to supply power
to the main processor and other components.

RK809 and RK817 are power management IC chips for multimedia products.
Most of their functions and registers are same, including the rtc.
