PATCH 1/1 soundwire: dmi-quirks: Disable ghost Realtek on Asus GX651AX

The Asus ROG Zephyrus Duo GX651AX exposes a Realtek RT722 device in ACPI which does not exist in the physical hardware. The device remains unattached while the CS42L43 and both CS35L56 devices attach successfully.

This confuses the function topology machine driver into creating duplicate DAI links named SDW3-Playback-SimpleJack, and the sof_sdw probe fails with error -12. Add a model-specific quirk to remove the ghost RT722 device.

Fixes 45cf24da0a10 ("ASoC: Intel: soc-acpi-intel-ptl-match: Remove unnecessary cs42l43 match")
