[PATCH 2/3] regulator: axp20x: Handle regulator_register returning ENODEV

Handle regulator_register returning ENODEV, this may happen when
the dts node for the regulator contains "status = disabled" which
is useful for the ldo_io regulators, to avoid the regulator code
getting in the way of gpio use of these pins.
