In preparation for adding additional DAIs to this component, convert the DAI driver definition to an array. Since this changes all of the lines in the definition anyway, let's move it closer to the ops function definitions, instead of on the far side of the DAPM arrays. And while moving the DAI driver ops, rename the set_fmt hook to match the usual naming scheme. Give the existing DAI an explicit ID and more meaningful stream names, so it will remain unique as more DAIs are added. The AIF widget streams must be updated to match.
