Judging from our downstream code, I don't actually expect all of
them will be used, except some being used yet not got upstream.

Downstream code groups those equivalents swgroups, so I think we
can do similarly using tegra_smmu_group_soc like the existing one
for display, if any of them gets upstream someday.
