soundwire: dmi-quirks: Disable ghost Realtek devices

Many systems ship with a Realtek audio codec in the ACPI that doesn't
physically exist in the system. This confuses the newer function
topology system that creates the soundcard, as it builds the card based
on the ACPI information.

Whilst we are working with the laptop vendors to try and stop this
happening there are quite a few systems where this has shipped. Add a
quirk to disable this "ghost" device.

Currently this patch should cover:
 - Asus UX5406AA
 - Lenovo Yoga Pro 9i (83SF)
 - Lenovo Yoga Slim 7 Ultra (83QK)
