BSP_AUDIO_IN_ConfigMicDefault() function

AUDIO_OK if correct communication, else wrong communication

Channel output Clock Divider and Filter Oversampling are calculated as follow: - Clock_Divider = CLK(input DFSDM)/CLK(micro) with 1MHZ < CLK(micro) < 3.2MHZ (TYP 2.4MHZ for MP34DT01TR) - Oversampling = CLK(input DFSDM)/(Clock_Divider * AudioFreq)
