ASoC: dsp - Add ASoC DSP core
This adds ASoC core support for internal and external DSPs and represents them
to the audio user as a CODEC like device with mixers, muxes and runtime audio
route changing.
The DSP core allows DSP DAIs to be dynamically re-routed at runtime between the
PCM device end (or Frontend - FE) and the physical DAI (Backend - BE) using
regular kcontrols (just like a hardware CODEC).
The DSP core also deal with DSP FE+BE suspend and resume PM ops.
