Is it okay to delay resuming codecs when resuming from S3? i.e. skip snd_hda_resume() in azx_resume()?
This would reduce driver resume time from S3. And the codecs will be resumed when being used for the 1st time after S3.
Resuming a codec may cost more than 100ms. So even if we parallel resuming codecs in snd_hda_resume(), driver resume time on some platforms is still a bit long.
