ASoC: compress: Add support for compress dai ops
ASoC Compress ops have only platform ops and no DAI ops unlike PCM device where we have both platform ops as well as DAI ops. So add compress dai ops and add this new structure to the ASoC core to make compressed devices a first class ASoC citizen Again like PCM ops, drivers are free to implement either or both of these ops based on device needs.
