Instead of using a custom binding for retrieving the GPIO that activates the LCD from devicetree, use a standard regulator. This approach has the advantage to be more generic. For example: in the case of a board that has a PMIC supplying the LCD voltage, the current approach would not work, as it only searches for a GPIO pin.
