[U-Boot] [PATCH 11/30] dm: sound: wm899c: Split out interface setup code

[sjg at google.com]

With driver model we want to do a minimal probe when the device is probed
and then set up the codec interface later when a sound is actully played.

Split this setup code out into its own function to help with this.
