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.

Required properties:

- compatible : Should be "fsl,imx31-sdma", "fsl,imx31-to1-sdma",

|
||||
"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.
