iommu: dma-mapping-fast: per-buffer coherent mappings
For "fast" stage 1 mappings add support to either force a buffer to
be mapped as coherent through the DMA_ATTR_FORCE_COHERENT DMA
attribute, or to force a buffer to not be mapped as coherent by
using the DMA_ATTR_FORCE_NON_COHERENT DMA attribute.
Both the DMA_ATTR_FORCE_COHERENT and DMA_ATTR_FORCE_NON_COHERENT DMA
attributes override the buffer coherency configuration set by making
the device coherent.
