pinctrl: split pincontrol states into its own header Move the pin control state defines into its own header file, since it is used both by machine.h which is facing the platform and by consumer.h which is facing the drivers, and pinctrl.h which is pinctrl-driver internal, let's not have each and every .h file include all others, then isolation is moot.

pinctrl: add sleep state definition There is an IDLE definition in the pinctrl framework, but for ux500 SLEEP is more apropriate. I've added some comments on the semantics of the common states so as to avoid misunderstandings. ChangeLog v1->v2: - Fixed terminology "on"->"into".
