From: Rob Clark <robdclark@xxxxxxxxxxxx>
When the special handling of qcom,adreno-smmu was moved into
qcom_smmu_create(), it was overlooked that we didn't have all the
required entries in qcom_smmu_impl_of_match. So we stopped getting
adreno_smmu_priv on sc7180, breaking per-process pgtables.
Fixes: 30b912a03d91 ("iommu/arm-smmu-qcom: Move the qcom,adreno-smmu check into qcom_smmu_create")
