ALSA: hda - resume codecs in parallel
To reduce driver resume time, this patch resumes the codecs in parallel
if there are multiple codecs on the bus.
- The PM workqueue of bus is also used to parallel resuming multiple codecs.
- The work item 'pm_work' is renamed to 'suspend_work' to parallel suspending
codecs.
- Add a work item 'resume_work' to parallel resuming codecs.
