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". Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
