arm64: dts: imx93-11x11-frdm: Add MQS audio support
Enable Medium Quality Sound (MQS) output on the i.MX93 FRDM 11x11 board
by adding sound card description and enabling sai1 and mqs1 dts nodes,
together with necessary clocks and pinmux.
This supports audio playback via SAI1 DAI which is connected to the MQS1
block.
