BUG=chrome-os-partner:30167
TEST=rk808 driver now gets built; future changes work

ARM: dts: Move the PMU interrupt pinctrl line to rk3288-evb common

The PMU interrupt pinctrl line was added to the rk3288-evb-act8846,
but it's the same line on both the ACT8846 version and the RK808
version.  This makes a lot of sense since they share the same SoC
daugherboard.  Move the pinctrl definition to the common file so we
can use it for the RK808 version.

BUG=chrome-os-partner:30167
TEST=Used by future change.

ARM: dts: Add rk808 PMIC to the rk3288-evb-rk808 dts file

This adds initial support.  For now, regulators are always on and we
don't specify the input supply for the regulators.

BUG=chrome-os-partner:30167
TEST=grep "" /sys/class/regulator/*/name shows all regulators
