DEV_OFF and DEV_OFF_RST functions for RK808 are designed error that
only DEV_OFF_RST can power off supplies. RK818 has been fixed this
issue, so that DEV_OFF is used to power off supplies.

When building with -Woverride-init, we get a warning about an incorrect
initializer:
drivers/mfd/rk808.c:244:8: error: initialized field overwritten [-Werror=override-init]
[RK818_IRQ_DISCHG_ILIM] = {
This is clearly a mistake, as both RK818_IRQ_DISCHG_ILIM and RK818_IRQ_USB_OV
are defined as '7', but they refer to different register bits. Changing
RK818_IRQ_DISCHG_ILIM to 15 is consistent with how all other 14 interrupts are
handled here, so I'm assuming this is what it should have been.

The RK818 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clocking
- Battery support
Both RK808 and RK818 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

Rk808 has a under voltage detect function, when the voltage of buck is
under 85% the target voltage, the buck output will reset. But if the
power load is too heavy, this function maybe err, when current over
4.2A, although the voltage is normal, but RK808 mistakenly think it is
under 85%, and reset the buck. So let's disable this function.

The RK808 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.
