The rt5682s codec can be pointed to through a sound-dai property to be
used as part of a machine sound driver. dtc expects #sound-dai-cells to
be defined in the codec's node in those cases, so add it in the
dt-binding and set it to 0.

Drop the entire last sentence, it's not really relevant to the problem.
What if we name compiler not dtc, but ctd? It's redundant and actually
forces reader to read unrelated stuff, instead of focusing on the root
problem - this is a DAI provider.
