[PATCH v3 05/17] arm64: dts: imx93-11x11-evk: Add MQS1 pinmux, clocks and mark conflicting devices

[Chancel Liu]

From: Chancel Liu <chancel.liu@xxxxxxx>

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. Also
describe the MQS output amplifier using the simple-audio-amplifier.
