What's the difference between imx6sx-sai and imx7d-sai?

I think you may put its compatible model in the DT instead of adding
a copy in the driver unless the SAI on the imx7d really has something
different.

For example:
	compatible = "fsl,imx6q-ssi", "fsl,imx51-ssi";
	/* The driver only has imx51-ssi */
