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.

That would definitely be awesome - looking forward to it!

Then instead of waiting for you to add that mode and then remove stuff later,
I'll just omit the `else: required:` block on v3, so that we avoid commit
noise and all the warnings when the deprecated check gets released.

I guess that's fine, right?
