mach-ux500: fix USB build error

From: Linus Walleij <[email protected]>

The mach-ux500/usb.c was referencing DMA macros, but not including <linux/dma-mapping.h> so it didn't compile. Fixed by a proper #include.

Arnd: please merge this atop of the st-ericsson stuff in arm-soc so that the -next tree compiles when it get pulled in.
