Document the dai-link subnodes and the audio-routing property, allowing to describe machine specific audio hardware and links in device tree. While at it, also deprecate the old properties which were previously used with the driver's partially hardcoded configuration. Also, since describing machine specific audio hardware and links replaces the now deprecated old logic doing the same in a driver hardcoded fashion, it is not allowed to have both the old and new properties together.
