ARM: mxs-dma: include <linux/dmaengine.h>

Other files using dma.h may fail to compile as follows:
In file included from sound/soc/mxs/mxs-pcm.h:22,
                 from sound/soc/mxs/mxs-saif.h:112,
                 from sound/soc/mxs/mxs-sgtl5000.c:34:

make: *** [sound] Error 2

It seems it's better for dma.h to include dmaengine.h himself.
