Rename CMA helpers to DMA helpers
---------------------------------
CMA (standing for contiguous memory allocator) is really a bit an accident of
what these were used for first, a much better name would be DMA helpers. In the
text these should even be called coherent DMA memory helpers (so maybe CDM, but
no one knows what that means) since underneath they just use dma_alloc_coherent.
