[PATCH 2/4] dt-bindings: iommu: mediatek: mt8195 Accept up to 5 interrupts

Some Mediatek IOMMU can have up to five interrupts so increase
the 'maxItems' to 5.

Fix the following dtb-check error:

mediatek/mt8395-radxa-nio-12l.dtb: infra-iommu at 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

Fixes: 3b5838d1d82e3 ("arm64: dts: mt8195: Add iommu and smi nodes")
