[PATCH 1/3] dt-bindings: dma: snps,dw-axi-dmac: Add CV1800B compatible

[Inochi Amaoto]

The DMA controller on CV1800B needs to use the DMA phandle args
as the channel number instead of hardware handshake number, so
add a new compatible for the DMA controller on CV1800B.

Change the DMA phandle args parsing logic so it can use handshake
number as channel number if necessary
