It seems extremely odd to me that the data delay would just happen to
end up meaning that inverting the clock works out to magically make
Still, if there really is a use-case for this in otherwise simple audio
systems, then I guess specifying all the DAI properties in sub-nodes is
indeed to simplest/most-flexible way to go.
