In addition to the primary ADSP stream ID, the DSP/SPF issues DMA transactions through extra stream IDs that are not covered by the existing single-entry mapping. Relax the iommus constraint to allow between 1 and 3 entries so the additional ML offload stream IDs can be described, fixing dtb_check schema violations on device trees that add them.
