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"

      "fsl,imx35-sdma", "fsl,imx35-to1-sdma", "fsl,imx35-to2-sdma"

      "fsl,imx51-sdma"

      "fsl,imx53-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.

- reg : Should contain SDMA registers location and length

- interrupts : Should contain SDMA interrupt

- #dma-cells : Must be <3>.
