ASoC: rt5682s: Stabilize the combo jack detection

Browse Source 
Changes:
1. Revise rt5682s_sar_power_mode and rt5682s_headset_detect to be more
   rational.
2. Manually set to the jack-unplugging state via rt5682s_headset_detect
   during going to suspend. Close unnecessary powers and prepare for
   re-detecting the CBJ during resuming.
3. Simplize rt5682s_resume.
