ALSA: hda: Refactor codec PM to use direct-complete optimization

Upon system resume, hda_codec_pm_resume() uses hda_codec_force_resume()
to resume the codec. However, pm_runtime_force_resume() won't really
resume the codec because of pm_runtime_need_not_resume() check.

Hence, hda_codec_force_resume() schedules a jackpoll work, which is to
really power up the codec.

Instead of doing that, we can use direct-complete to make the PM flow
more straightforward, and keep codec always suspended through system PM
flow if conditions are met.

On system suspend, PM core will decide what to do based on
hda_codec_pm_prepare():
- If codec is not runtime-suspended, PM core will suspend and resume the
device as normal.
- If codec is runtime-suspended, PM core will try to keep it suspended.
If it's still suspended after system resume, we use
hda_codec_pm_complete() to resume codec if it's needed.
