any range not listed is left unused. Add iommu-ranges to the compute-cb subnode properties so the DT validator accepts it on context bank nodes. Relax #address-cells to enum: [1, 2] and #size-cells to enum: [0, 2] to allow platforms that require 64-bit values in iommu-ranges to pass binding validation.
