[PATCH v3 10/17] arm64: dts: imx943-evk: Add MQS1 pinmux, clocks and mark conflicting devices

[Chancel Liu <chancel.liu@oss.nxp.com>]

From: Chancel Liu <chancel.liu@nxp.com>

MQS1 shares pins with PDM and its sound card conflicts with the WM8962
sound 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.
