The LP55xx driver is already using the of_gpio() functions to pick a global GPIO number for "enable" from the device tree and request the line. Simplify it by just using a GPIO descriptor. Make sure to keep the enable GPIO line optional, change the naming from "lp5523_enable" to "LP55xx enable" to reflect that this is used on all LP55xx LED drivers.
