arm64: dts: rockchip: fix dma-controller node names on rk356x

DMA-Cotrollers defined in rk356x.dtsi do not match the pattern in bindings.

arch/arm64/boot/dts/rockchip/rk3568-evb1-v10.dt.yaml:
  dmac@fe530000: $nodename:0: 'dmac@fe530000' does not match '^dma-controller(@.*)?$'
	From schema: Documentation/devicetree/bindings/dma/arm,pl330.yaml
arch/arm64/boot/dts/rockchip/rk3568-evb1-v10.dt.yaml:
  dmac@fe550000: $nodename:0: 'dmac@fe550000' does not match '^dma-controller(@.*)?$'
	From schema: Documentation/devicetree/bindings/dma/arm,pl330.yaml

This Patch fixes it.
