[PATCH] linux/dma-mapping.h needs linux/device.h

It seems that most architectures already include linux/device.h in their
own asm/dma-mapping.h.  Most but not all, and some drivers fail to
compile on those architectures that don't.  Since everybody needs it
let's include device.h from one place only and fix compilation for
everybody.
