iommu/vt-d: Implement map/unmap_pages() iommu_ops callback

Implement the map_pages() and unmap_pages() callback for the Intel IOMMU
driver to allow calls from iommu core to map and unmap multiple pages of
the same size in one call. With map/unmap_pages() implemented, the prior
map/unmap callbacks are deprecated.
