MT8186 has 4 iommus in the list, to cope with this situation, adjust the maxItems to 4 (instead of previous 2). Add also minItems as 1 since iommus are mandatory, to avoid warning on the example.

If IOMMU is required, then 'required' is where that is defined. Is there a case where 1 IOMMU is valid? If so, what h/w has this case. Rob
