[PATCH v4 2/3] dt-bindings: remoteproc: qcom,shikra-pas: Add iommus constraints

[Komal Bajaj]

Add iommus constraints for Shikra PAS compatible:
- qcom,shikra-cdsp-pas: maxItems: 1
- qcom,shikra-lpaicp-pas: minItems: 3, maxItems: 3

CDSP uses single IOMMU stream, while LPAICP firmware uses three.
These are needed to describe the firmware streams when Linux boots
at EL2 without the hypervisor.
