From: Shengjiu Wang <shengjiu.wang@xxxxxxx> SAI has 4 clock sources, which can be selected using MSEL bit of SAI TCR2 register. On imx6/7 mclk0 and mclk1 always point to the same clock source. Anyhow, this is no longer true for imx8. For this reason, we need to add mclk0 and handle it in a generic way in SAI driver.
