[ Upstream commit 42314738906380cbd3b6e9caf3ad34e1b2d66035 ]
Add the compatible for the separate IOMMU on SDM670 for the Adreno GPU.
This IOMMU has the compatible strings:
"qcom,sdm670-smmu-v2", "qcom,adreno-smmu", "qcom,smmu-v2"
While the SMMU 500 doesn't need an entry for this specific SoC, the
SMMU v2 compatible should have its own entry, as the fallback entry in
arm-smmu.c handles "qcom,smmu-v2" without per-process page table support
unless there is an entry here. This entry can't be the
"qcom,adreno-smmu" compatible because dedicated GPU IOMMUs can also be
SMMU 500 with different handling.
