The current null-pointer check in __dma_alloc_coherent and
__dma_free_coherent is not needed anymore since the
__dma_alloc/__dma_free functions won't be called if !dev (dummy ops will
be called instead).

StreamIDs. However, we have to apply a mask (the ARM SMMU spec allows
for this) to the StreamIDs due to limited number of StreamID 2 Context

represent this in the DT like this:
