[PATCH] soundwire: dmi-quirks: Disable ghost Realtek on Lenovo Pro 9

[Charles Keepax]

The Lenovo Pro 9 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.
