ALSA: hda: Introduce HOST stream setup mechanism
HDAudio stream setup procedure differs between revisions of the
controller device. Currently the differences are handled directly within
AudioDSP platform drivers with if-statements. Implement a more generic
approach and expose a function that a platform driver may use to ensure
the correct procedure is followed each time.
