[PATCH v2 3/4] dt-bindings: iommu/arm,smmu: add compatible string for Marvell

[Gregory CLEMENT <gregory.clement@xxxxxxxxxxx>]

From: Hanna Hawa <hannah@xxxxxxxxxxx>

Add specific compatible string for Marvell usage due 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.
