[PATCH v2 1/3] dt-bindings: remoteproc: qcom,pas-common: allow up to 3 iommus

[Pratyush Meduri]

The ADSP PAS on several Qualcomm SoCs (e.g. SA8775P/lemans, QCS8300,
Monaco) needs more than a single SMMU stream ID for the audio ML
(machine-learning) offload use case. 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.
