Device-Tree bindings for Active-semi ACT8945A MFD driver

Required properties:
 - compatible: "active-semi,act8945a".
 - reg: the I2C slave address for the ACT8945A chip

The chip exposes two subdevices:
 - a regulators: see ../regulator/act8945a-regulator.txt
 - a charger: see ../power/act8945a-charger.txt
