[PATCH v4 3/5] arm64: dts: mediatek: mt8173: Add mediatek,infracfg phandle for IOMMU

[AngeloGioacchino Del Regno]

The IOMMU driver now looks for the "mediatek,infracfg" phandle as a
new way to retrieve a syscon to that:
even though the old way is retained, it has been deprecated and the
driver will write a message in kmsg advertising to use the phandle
way instead.

For this reason, assign the right phandle to mediatek,infracfg in
the iommu node.
