ASoC: fsl_sai: Add RX/TX BCLK swap support
Add support for setting the Bit Clock Swap bit in CR2 register
via new "fsl,sai-bit-clock-swap" DT property. This bit swaps the
bit clock used by the transmitter or receiver in asynchronous mode,
i.e. makes transmitter use RX_BCLK and TX_SYNC, and vice versa,
makes receiver use TX_BCLK and RX_SYNC.
