DMA address translation requires a dma-ranges property in bus nodes. While some operating systems work around the absence of such property in an attempt to implement compatibility with incorrect DT, the property is nonetheless required. Add the dma-ranges property to the /soc node that contains all on-SoC peripherals. The bus supports 40-bit DMA addressing without any address translation.
