iommu/amd: Add map/unmap_pages() iommu_domain_ops callback support

Implement the map_pages() and unmap_pages() callback for the AMD IOMMU
driver to allow calls from iommu core to map and unmap multiple pages.
Also deprecate map/unmap callbacks.

Finally gatherer is not updated by iommu_v1_unmap_pages(). Hence pass
NULL instead of gather to iommu_v1_unmap_pages.
