[PATCH 10/20] dt-bindings: arm-smmu: Add compatible string for Adreno GPU SMMU

[Rob Clark]

From: Jordan Crouse <jcrouse@xxxxxxxxxxxxxx>

Every Qcom Adreno GPU has an embedded SMMU for its own use. These
devices depend on unique features such as split pagetables,
different stall/halt requirements and other settings. Identify them
with a compatible string so that they can be identified in the
arm-smmu implementation specific code.
