[PATCH 03/10] arm: dts: owl-s500: Add DMA controller

Add DMA controller node for Actions Semi S500 SoC.

Note the Actions Semi Owl SoC's DMA driver seems to be fully compatible
with the Actions Semi S500 SoC, even though this is not explicitly
mentioned in the source code. Hence, for the moment, enable the DMA
controller node using the "actions,s900-dma" compatible string.
