ASoC: bolero: Add concurrency support on audio capture path

Browse Source 
During voice activation and audio capture concurrency usecase,
there is no common reference count for DMIC clock enablement,
results into mute when one usecase tears down. Change enables
a common reference count in bolero codec driver between voice
activation usecase and audio capture usecase to avoid mute
during VA and audio capture concurrency.
