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

Signed-off-by: Emilio López <emilio@elopez.com.ar>
Reviewed-by: Chen-Yu Tsai <wens@csie.org>

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.
