We see odd FIFO overruns with this, we assume the best thing to do is to disable the RX I2S frontend first, and then disable the FIFO that is using it. This also fixes an issue where using multi-word frames (TDM) have partial samples stuck in the FIFO which then get read out when the next capture is started.
