soundwire: dmi-quirks: Disable ghost Realtek on Asus Expertbook

Browse Source 
The Asus Expertbook B9406CAA also has a Realtek device in the ACPI that
doesn't exist in the physical hardware. This confuses the machine driver
into attempting to create DAI links for the device. Add a quirk to
remove this device.
