ARM: ux500: tidy up pin sleep modes
Browse files Browse the repository at this point in the history 
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.
