ARM: ux500: Pass MSP DMA platform data though AUXDATA
It isn't currently possible to pass all platform specific configuration
though Device Tree. Thinks like device names used in the clock
infrastructure, call-backs and DMA information have to be passed in via
AUXDATA structures and the MSP is no exception. Here we're passing DMA
settings.
