iommu: Add DMA mapping operations
In order to support IOMMUs in non-bypass mode we need device ops
to map and unmap DMA memory. The map operation enters a mapping
for a region specified by CPU address and size into the translation
table of the IOMMU and returns a DMA address suitable for
programming the device to do DMA. The unmap operation removes
this mapping from the translation table of the IOMMU.
