arm64: dts: mediatek: mt8195: revise VDOSYS RDMA node name

[ Upstream commit 52f4a10f2a860402c130c5c21d055e721d63a7e9 ]

DMA-related nodes have their own standardized naming. Therefore,
the MT8195 VDOSYS RDMA has been unified and corrected.
Additionally, these modifications will facilitate the further
integration of bindings.
