Subject: [PATCH 13/14] dt-bindings: dma: dma350: Support ARM DMA-250

Compared with ARM DMA-350, DMA-250 is a simplified version, they share
many common parts, but they do have difference. The difference will be
handled in next driver patch, while let's add DMA-250 compatible string
to dt-binding now.
