Subject: [PATCH v2] ASoC: dt-bindings: imx-audio-spdif: convert to YAML

Convert the imx-audio-spdif binding to YAML.

When testing dtbs_check, found below compatible strings
are not listed in document:

fsl,imx-sabreauto-spdif
fsl,imx6sx-sdb-spdif

So add them in yaml file to pass the test.

changes in v2:
- change file name to imx-spdif.yaml
- remove |
- add anyof for spdif-in and spdif-out requirement
- change example name to sound

-Required properties:
-
-  - compatible		: "fsl,imx-audio-spdif"
-
-  - model		: The user-visible name of this sound complex
-
-  - spdif-controller	: The phandle of the i.MX S/PDIF controller

-Optional properties:

-			  or jack on the board or it's connecting to some

-
-  - spdif-in		: This is a boolean property. If present, the receiving

-			  is a physical S/PDIF in connector/jack on the board.
-
-* Note: At least one of these two properties should be set in the DT binding.

-Example:
-
-sound-spdif {
