Samuel Holland 967499870f power: regulator: Add a driver for the AXP PMIC drivevbus
AXP PMICs have a pin which can either report the USB VBUS state, or
driving a regulator that supplies USB VBUS. Add a regulator driver for
controlling this pin. The selection between input and output is done via
the x-powers,drive-vbus-en pin on the PMIC (parent) node.
