mfd: rk8xx: Add RK816 support

This integrates RK816 support in the this existing rk8xx mfd driver.

This version has unaligned interrupt registers, which requires to define a
separate get_irq_reg callback for the regmap. Apart from that the
integration is straightforward and the existing structures can be used as
is. The initialization sequence has been taken from vendor kernel.

mfd: rk808: Fix RK818 ID template

The Rockchip PMIC driver can automatically detect connected component
versions by reading the ID_MSB and ID_LSB registers. The probe function
will always fail with RK818 PMICs because the ID_MSK is 0xFFF0 and the
RK818 template ID is 0x8181.

This patch changes this value to 0x8180.

RK805 has SLEEP signal, which can put the device into SLEEP or OFF
mode. The default is SLEEP mode.

However, when the kernel performs power-off (actually the ATF) the
device will not go fully off and this will result in higher power
consumption and inability to wake the device with RTC alarm.

The solution is to enable pm_power_off_prepare function, which will
configure SLEEP pin for OFF function.

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
