[PATCH v2 09/16] riscv: dts: canaan: add a specific compatible for k210's dma

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

The DMAC on the k210 has a non standard interrupt configuration, which
leads to dtbs_check warnings:

k210_generic.dtb: dma-controller at 50000000: interrupts: [[27], [28], [29], [30], [31], [32]] is too long
>From schema: Documentation/devicetree/bindings/dma/snps,dw-axi-dmac.yaml

Update the binding to use a custom compatible to avoid the warning.
