ASoC: fsl: add imx-sgtl5000 machine driver
This is the initial imx-sgtl5000 machine driver support with only playback dai link implemented. More features can be added on top of it later. It's a device tree only machine driver working with fsl_ssi driver.

+Freescale i.MX audio complex with SGTL5000 codec
+
+Required properties:
+- compatible : "fsl,imx-audio-sgtl5000"
+- model : The user-visible name of this sound complex
+- ssi-controller : The phandle of the i.MX SSI controller
+- audio-codec : The phandle of the SGTL5000 audio codec
+- mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
+- mux-ext-port : The external port of the i.MX audio muxer
+
+Note: The AUDMUX port numbering should start at 1, which is consistent with
+hardware manual.
+
+Example:
+
+sound {
+ compatible = "fsl,imx51-babbage-sgtl5000",
+ "fsl,imx-audio-sgtl5000";
+ model = "imx51-babbage-sgtl5000";
+ ssi-controller = <&ssi1>;
+ audio-codec = <&sgtl5000>;
+ mux-int-port = <1>;
+ mux-ext-port = <3>;
+};
