arm64: dts: mediatek: mt8192: Add missing dma-ranges to soc node

In the series "Adjust the dma-ranges for MTK IOMMU", the mtk-iommu
driver was adapted to separate the iova range based on the larb used,
and a dma-ranges property was added to the soc node in the devicetree of
the affected SoCs allowing the whole 16GB iova range to be used. Except
that for mt8192, there was no patch adding dma-ranges.

Add the missing dma-ranges property to the soc node like was done for
mt8195 and mt8186. This fixes the usage of the vcodec, which would
otherwise trigger iommu faults.
