The A10S and A13 SoCs have sun4i-compatible DMA controllers. Let's add
the corresponding nodes to represent them on the device tree.

Changes from v2:
* Fix whitespace
* Collect tag from Chen-Yu
Note that I have only tested on A10S, if anyone with an A13 device could
test as well, that would be great! I don't expect any issues however.
