dma: imx-sdma: Add ROM script addresses to driver
This adds the ROM script addresses for i.MX25, i.MX5x and i.MX6 to the SDMA driver needed for the driver to work without additional firmware. The ROM script addresses are SoC specific and in some cases even tapeout specific. This patch adds the ROM script addresses only for SoCs which do not have a tapeout specific SDMA ROM, because currently it's unclear how this case should be handled.

* Freescale Smart Direct Memory Access (SDMA) Controller for i.MX
Required properties:
-- compatible : Should be "fsl,<chip>-sdma"
+- 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.
- reg : Should contain SDMA registers location and length
- interrupts : Should contain SDMA interrupt
- #dma-cells : Must be <3>.
