There are no architectures left defining their own dma_alloc/dma_free.
Instead, they define DMA_ALIGNMENT and use <dma.h>'s common
implementation.
This will be useful later on, as we can use DMA_ALIGNMENT for sanity
checking with CONFIG_DMA_DEBUG_API. Till then, ensure we get no new
architecture-specific definitions of dma_alloc/dma_free, by preventing
override of the <dma.h> implementation.
