ASoC: qcom: sc7180: fix 32 bit format for adau7002

Browse source 
the microphone is attached to external codec(adau7002)
instead of rt5682.We need to always use 32 bit format on sc7180
to meet the clock requirement of adau7002:
The ADAU7002 requires a BCLK rate
that is a minimum of 64× the LRCLK sample rate
