pinctrl: Do not depend in GPIOLIB, select it

Instead of depends on GPIOLIB and having to run around in
Kconfig menus looking for why your device is not available,
simply select it from the pin control drivers that need it.

The Kconfig for GPIOLIB is improved, selectable and this
should "just work".
