pinctrl: lochnagar: select GPIOLIB

commit f7e36e18946b4ec756b9c5cf4fb8891be8d1e4a3 upstream.

In a rare randconfig build I came across one configuration that does
not enable CONFIG_GPIOLIB, which is needed by lochnagar:

ERROR: "devm_gpiochip_add_data" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!
ERROR: "gpiochip_generic_free" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!
ERROR: "gpiochip_generic_request" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!
ERROR: "gpiochip_get_data" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!

Add another 'select' like all other pinctrl drivers have.
