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".

/**

 * @PINCTRL_STATE_DEFAULT: the state the pinctrl handle shall be put

 *	into as default, usually this means the pins are up and ready to

 *	be used by the device driver. This state is commonly used by

 *	hogs to configure muxing and pins at boot.

 * @PINCTRL_STATE_IDLE: the state the pinctrl handle shall be put into

 *	when the pins are idle. Could typically be set from a

 *	pm_runtime_suspend() operation.

 * @PINCTRL_STATE_SLEEP: the state the pinctrl handle shall be put into

 *	when the pins are sleeping. Could typically be set from a

 *	common suspend() function.
