dma: sdma: Add imx25 compatible
imx25 did not work without a firmware previously. This patch adds a DT compatible to pass the correct data with the default script addresses for imx25. Add imx25 compatible to the list of compatibles in the binding documentation.

* Freescale Smart Direct Memory Access (SDMA) Controller for i.MX
Required properties:
-- compatible : Should be "fsl,imx31-sdma", "fsl,imx31-to1-sdma",
- "fsl,imx31-to2-sdma", "fsl,imx35-sdma", "fsl,imx35-to1-sdma",
- "fsl,imx35-to2-sdma", "fsl,imx51-sdma", "fsl,imx53-sdma" or
- "fsl,imx6q-sdma". The -to variants should be preferred since they
- allow to determnine the correct ROM script addresses needed for
- the driver to work without additional firmware.
+- compatible : Should be one of
+ "fsl,imx25-sdma"
+ "fsl,imx31-sdma", "fsl,imx31-to1-sdma", "fsl,imx31-to2-sdma"

- reg : Should contain SDMA registers location and length
- interrupts : Should contain SDMA interrupt
- #dma-cells : Must be <3>.
