A RISC-V platform can have both DMA coherent/noncoherent devices. Since the RISC-V architecture is marked coherent, devices should be marked as noncoherent when coherent devices exist. Add dma-noncoherent property for snps,dw-axi-dmac device. It will be used on SG2044, and it has other coherent devices.
