[PATCH] pinctrl: sunxi: select GPIOLIB

[Icenowy Zheng]

Allwinner pin controllers are also GPIO controllers.

Currently, if GPIOLIB is forgot to be chosen, the build of
pinctrl-sunxi.c will fail for lacking a lot of gpiochip_* functions.

Select GPIOLIB to ensure this driver can be built.

This bug is found when I try to add sunxi drivers on an ARM64
allnoconfig, in order to prove that sunxi-ng ccu driver depends on
reset_controller framework.

I proved the latter dependency, but how to satisfy it still needs
some discussion.
