regulator: lp872x: Add enable GPIO pin support
LP872x regulators are made active via the EN pin, which might be hooked to a GPIO. This adds support for driving the GPIO high when the driver is in use. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
