With this patch, DMA has a chance of probing and doing something
useful.

Signed-off-by: Felipe Balbi <felipe.balbi@microsoft.com>

Changes since v1:

	- Remove dmas property from spi0 (will be added later as a
          separate patch

	- Correct dma unit name to dma-controller

	- Correct binding order (compatible, reg, dma-cells at the end)
