Subject: [PATCH v3 1/6] dt-bindings: arm-smmu: Use qcom,smmu compatible for
 MMU500 adreno SMMUs

qcom,smmu-500 was introduced to prevent people from adding new
compatibles for what seems to roughly be the same hardware. Use it for
qcom,adreno-smmu-compatible targets as well.

While at it, fix the "arm,smmu-500" -> "arm,mmu-500" typo in the comment.
