iommu/virtio: Add map/unmap_pages() callbacks implementation

Browse source

Map/unmap_pags() allows map and unmap multiple pages of the same size
in one call, which can improve performance by reducing the numbers of
vmexits. With map/unmap_pages() implemented, the prior map/unmap()
callbacks are deprecated.
