[PATCH] regulator: rpi-panel-v2: Add missing GPIOLIB dependency

[Marek Vasut]

Add missing GPIOLIB dependency reported by the LKP test robot.
This fixes the following report:

"
kismet warnings: (new ones prefixed by >>)
>> kismet: WARNING: unmet direct dependencies detected for GPIO_REGMAP when selected by REGULATOR_RASPBERRYPI_TOUCHSCREEN_V2
   WARNING: unmet direct dependencies detected for GPIO_REGMAP
     Depends on [n]: GPIOLIB [=n]
     Selected by [y]:
     - REGULATOR_RASPBERRYPI_TOUCHSCREEN_V2 [=y] && REGULATOR [=y] && I2C [=y]
"
