[PATCH 2/4] ARM: dma: define DMA_ALIGNMENT instead of defining dma_alloc

[Ahmad Fatoum]

There's a suitable fallback dma_alloc implementation already in dma.h,
which we can use as soon as we define DMA_ALIGNMENT. By doing that, we
also can use the __dma_aligned attribute that will come in handy in the
follow-up commit.
