iommu/amd: Correctly encode huge pages in iommu page tables

commit d4b036648402bb4ef6d4a0df51375a2fb705b6cc upstream.

When a default page-size for given level should be mapped,
the level encoding must be 0 rather than 7. This fixes an
issue seen on IOMMUv2 hardware, where this encoding is
enforced.
