Subject: [PATCH v3 2/7] dt-bindings: memory: mtk-smi: No need mediatek,larb-id for mt8167

Mute the warning from "make dtbs_check":

larb@...16000: 'mediatek,larb-id' is a required property
	arch/arm64/boot/dts/mediatek/mt8167-pumpkin.dt.yaml
larb@...01000: 'mediatek,larb-id' is a required property
	arch/arm64/boot/dts/mediatek/mt8167-pumpkin.dt.yaml
larb@...10000: 'mediatek,larb-id' is a required property
	arch/arm64/boot/dts/mediatek/mt8167-pumpkin.dt.yaml

As the description of mediatek,larb-id, the property is only
required when the larbid is not consecutive from its IOMMU point of view.

Also, from the description of mediatek,larbs in
Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml, all the larbs
must sort by the larb index.

In mt8167, there is only one IOMMU HW and three larbs. The drivers already
know its larb index from the mediatek,larbs property of IOMMU, thus no
need this property.
