Currently DMIC capture and WoV usecase uses same BE DAI but operate at different sampling rates, this results in config mismatch for WoV when DMIC is already running in parallel.
DMIC has two slots which can operate with some constraints, so add BE DAI for DMICvoice pin which can used for WoV usecases to capture 4ch, 16KHz, 16bit data.
