The idea is to provide all possible formats and rates to the ASoC core 
at the DAI registration phase. Then at the stream startup the currently 
valid ELD is scanned and and ALSA constraints are set according to it 
(with snd_pcm_hw_constraint_eld()).

Russell already listed why the component interface is not good for 
registering optional subsystems. Any particular reason why passing 
function pointers over pdata should be considered bad? Can you suggest 
an alternative?
