ASoC: rt5682s: Reduce coupling of Micbias and Vref2 settings 

Some parts of rt5682s CCF function are implemented by
'MICBIAS' and 'Vref2' dapm widgets.

There is a risk of causing not expected behavior if we
mix using dapm and CCF operations in machine specific code.
This patch reduces the coupling.
