[PATCH v6 2/2] riscv: dts: sophgo: cv180x: Allow the DMA multiplexer to set channel number for DMA controller

[Inochi Amaoto]

Change the DMA controller compatible to the sophgo,cv1800b-axi-dma,
which supports setting DMA channel number in DMA phandle args.

This dts change does not break backward compatibility as a fallback
compatiable string is added.
