Merge branch 'for-next/iommu/misc' into for-next/iommu/core

Miscellaneous IOMMU changes for 5.11. Largely cosmetic, apart from a
change to the way in which identity-mapped domains are configured so
that the requests are now batched and can potentially use larger pages
for the mapping.

* for-next/iommu/misc:
  iommu/io-pgtable-arm: Remove unused 'level' parameter from iopte_type() macro
  iommu: Defer the early return in arm_(v7s/lpae)_map
  iommu: Improve the performance for direct_mapping
  iommu: return error code when it can't get group
  iommu: Modify the description of iommu_sva_unbind_device
