From: Chancel Liu <redacted> MQS1 shares pins with PDM and its sound card conflicts with the BT SCO card. Add the MQS1 pinctrl group and label the conflicting device and card so the shared imx9-mqs overlay can disable them. The overlay and its Makefile rule are added in a later patch. Update SAI1 clock assignments to provide the MQS MCLK source.
