regulator: rpi-panel-attiny: add back GPIOLIB dependency

This driver provides a gpio chip, which is only possible when GPIOLIB
is enabled, which was previously guaranteed by the CONFIG_OF_GPIO
dependency that is now gone:

ERROR: modpost: "gpiochip_get_data" [drivers/regulator/rpi-panel-attiny-regulator.ko] undefined!
ERROR: modpost: "devm_gpiochip_add_data_with_key" [drivers/regulator/rpi-panel-attiny-regulator.ko] undefined!

Add an explicit GPIOLIB dependency instead.
