[PATCH] ARM: ux500: tidy up pin sleep modes

[Linus Walleij]

From: Linus Walleij <linus.walleij at linaro.org>

This named the sleep mode pin configurations as *slpm* rather
than *sleep* to correspond better with the settings from the
datasheet. It also defines an optional sleep mode for the SPI
controller SPI2.

Arnd, Olof: again a patch I'd like to take through the pinctrl
tree for simplicity.
