Newer Matebook D14 model comes with essx8336 and supports SOF, but the initial models use the legacy driver, with a Realtek ALC 256 AC97 chip on it.
The BIOS seems to be prepared to be used by both models, so it contains an entry for ESSX8336 on its DSDT table.
Add a quirk, as otherwise dspconfig driver will try to load SOF, causing audio probe to fail.

Worth to mention that I opened an issue on Github about that:
https://github.com/thesofproject/linux/issues/4934
I added there the ACPI DSDT table as a reference.
