[PATCH] dt-bindings: iommu: arm,smmu: document clocks for the SM8350 GPU SMMU

[Krzysztof Kozlowski]

Document the clocks for Qualcomm SM8350 Adreno GPU SMMU, already used in
DTS:

  sm8350-hdk.dtb: iommu@3da0000: clock-names: False schema does not allow ['bus', 'iface', 'ahb', 'hlos1_vote_gpu_smmu', 'cx_gmu', 'hub_cx_int', 'hub_aon']
