[PATCH v2 09/10] arm64: allwinner: a64: Add device node for DMA controller

["Stefan Brüns" <stefan.bruens-vA1bhqPz9FBZXbeN9DUtxg@public.gmane.org>]

The A64 SoC has a DMA controller that supports 8 DMA channels
to and from various peripherals. The last used DRQ port is 27.

Add a device node for it.
