[PATCH v2 1/2] dt-bindings: media: mediatek-jpeg-encoder: change max iommus count

[Eugen Hristev]

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.

maxItems alone means minItems is the same size. 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.
