[PATCH] mach-ux500: fix USB build error

[Linus Walleij]

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

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.
