dmaengine: sun6i: Add driver for the Allwinner A31 DMA controller
The Allwinner A31 has a 16 channels DMA controller that it shares with the newer A23. Although sharing some similarities with the DMA controller of the older Allwinner SoCs, it's significantly different, I don't expect it to be possible to share the driver for these two. The A31 Controller is able to memory-to-memory or memory-to-device transfers on the 16 channels in parallel.
