Linus Walleij 28a8d14cc7 pinctrl: break out a pinctrl consumer header
This breaks out a <linux/pinctrl/consumer.h> header to be used by
all pinmux and pinconfig alike, so drivers needing services from
pinctrl does not need to include different headers. This is similar
to the approach taken by the regulator API.
