Joseph Chen 94a7fc2cbd mfd: rk808: power off system in syscore shutdown
For PMIC that power off supplies by write register via i2c bus,
it's better to do power off at syscore shutdown.

Because when run to kernel's "pm_power_off" call, i2c may has
been stopped or PMIC may not be able to get i2c transfer while
there are too many devices are competiting.

This patch effects on PMIC: RK808/RK818/RK816, not including RK805
which power off system by pull up pmic sleep pin in ATF.
