Add a callback for IOMMU drivers to provide a path for the IOMMU framework to call into an IOMMU driver, which can call into the io-pgtable code, to map a physically contiguous rnage of pages of the same size. For IOMMU drivers that do not specify a map_pages() callback, the existing logic of mapping memory one page block at a time will be used.
