dt-bindings: dma: snps,dw-axi-dmac: Allow devices to be marked as noncoherent 



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.
