[PATCH 2/6] dt-bindings: iommu: mediatek: Fix interrupt count constraint for new SoCs

The infra-iommu node in mt8195.dtsi was triggering a CHECK_DTBS error due
to an excessively long 'interrupts' property. The error message was:

infra-iommu@10315000: interrupts: [[0, 795, 4, 0], [0, 796, 4, 0],
[0, 797, 4, 0], [0, 798, 4, 0], [0, 799, 4, 0]]
is too long

To address this issue, add "minItems: 1" and "maxItems: 5" constraints to
the 'interrupts' property in the DT binding schema. This change allows for
flexibility in the number of interrupts for new SoCs

Fixes: bca28426805d ("dt-bindings: iommu: mediatek: Convert IOMMU to DT schema")
