ALSA: hda - Move codec suspend/resume to codec driver
This patch moves the suspend/resume mechanisms down to each codec
driver level, as we have a proper codec driver bound on the bus now.
Then we get the asynchronous PM gratis without fiddling much in the
driver level.
As a soft-landing transition, implement the common suspend/resume pm
ops for hda_codec_driver and keep the each codec driver intact. Only
the callers of suspend/resume in the controller side (azx_suspend()
and azx_resume()) are removed.
Another involved place is azx_bus_reset() calling the temporary
suspend and resume as a hackish method of bus reset. The HD-audio
core provide a helper function snd_hda_bus_reset() instead.
