ASoC: rt5682s: Fix the wrong jack type detected

Browse Source 
Some powers were changed during the jack insert detection and clk's
enable/disable in CCF.
If in parallel, the influence has a chance to detect the wrong jack
type.

We refer to the below commit of the variant codec (rt5682) to fix
this issue.
  ASoC: rt5682: Fix deadlock on resume

1. Remove rt5682s_headset_detect in rt5682s_jd_check_handler and
   use jack_detect_work instead of.
2. Use dapm mutex used in CCF to protect most of jack_detect_work.
