iommu_pt: support small VA for AMDv1
When hardware/VM request a small VA limit, the generic page-table code
clears PT_FEAT_DYNAMIC_TOP. This later causes domain initialization to
fail with -EOPNOTSUPP.
Remove the clearing so init succeeds when the VA fits in the starting
level and no top-level growth is needed.
