The DMA IP of Sophgo CV18XX/SG200X is based on a DW AXI CORE, with
an additional channel remap register located in the top system control
area. The DMA channel is exclusive to each core.
In addition, the DMA multiplexer is a subdevice of system controller,
so this binding only contains necessary properties for the multiplexer
itself.
Add the dmamux binding for CV18XX/SG200X series SoC.
