iommu/amd: Convert to using amd_io_pgtable
Make use of the new struct amd_io_pgtable in preparation to remove the struct domain_pgtable. Signed-off-by: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com> Link: https://lore.kernel.org/r/20201215073705.123786-5-suravee.suthikulpanit@amd.com Signed-off-by: Joerg Roedel <jroedel@suse.de>
