ASoC: mbhc: Fix audio mute for special headset

Browse source 
MICBIAS is disabled extra time during playback session
resulting in mclk also being disabled. This results
in slimbus overflow and audio mute. This can be fixed
by checking whether device connected is special headset
before disabling micbias during report_plug so that
micbias is not disabled again.
