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.

Should be "-gpios" instead of "-gpio".

Care to comment why? There is only one GPIO that can be used here, since
there is only one single EN pin. I thought this matched what is done
already with "ti,dvs-gpio".

To be consistent. We use "clocks" and "interrupts" always whether one
or more for example.

-gpio is documented as deprecated now.
