The device tree binding needs a property to reference it. Without a reference for the implementation to properly configure the IOMMU, it will fault and cause the video decoder to fail. Add an "iommus" property for referring to the IOMMU port. The master ID in the example is taken from the IOMMU fault error message on Linux, and the number seems to match the order in the user manual's IOMMU diagram.
