Naming is not aligned with a namespace.

I would rather name it dev_pinctrl() and locate it in pinctrl/devinfo.h.

Can be simplified with help of Elvis:

	p = bri->pinctrl ?: dev_pinctrl(dev->parent);

All the same about Linus W., who is pin control subsystem maintainer, and be
sure the respective mailing lists are also included.
