[PATCH v4 3/4] dt-bindings: arm-smmu: add compatible string for Marvell Armada-AP806 SMMU-500
Add specific compatible string for Marvell usage due to errata of accessing 64bits registers of ARM SMMU, in AP806. AP806 SoC uses the generic ARM-MMU500, and there's no specific implementation of Marvell, this compatible is used for errata only.
