ARM: dts: imx6qdl-tx6: remove undocumented karo,imx6qdl-tx6-sgtl5000 and keep only...

Remove the undocumented and unused compatible karo,imx6qdl-tx6-sgtl5000 and
retain only the generic simple-audio-card sound configuration.

The karo,imx6qdl-tx6-sgtl5000 compatible is not documented and is not
referenced by any in-kernel driver. The audio setup is already fully
described using simple-audio-card, which is the standard and supported
binding for this hardware configuration.

No known users (such as uboot) rely on karo,imx6qdl-tx6-sgtl5000.

Fix below CHECK_DTBS warnings:
arch/arm/boot/dts/nxp/imx/imx6dl-tx6dl-comtft.dtb: /sound: failed to match any schema with compatible: ['karo,imx6qdl-tx6-sgtl5000', 'simple-audio-card']
