If we want to get more complex usage of clocks in the DT we should be
moving the CODECs over to using the standard clock bindings for this
stuff rather than inventing custom ASoC clock bindings for it.  That way
we don't have to deal with the pain of trying to join things up in the
future.

As a practical matter we also don't have any CODECs specifying any
bindings for ASoC level clock IDs right now either.
