[PATCH 1/3] pinctrl: split off consumer API into linux/pinctrl/consumer.h

[Ahmad Fatoum]

Follow-up patches will align the barebox pinctrl consumer API with
Linux'. So it makes sense to have the header called the same as well.
Users of the old pinctrl.h header are unaffected as it will include
the new <linux/pinctrl/consumer.h>.
