Commit a9c4a912b7dc ("ACPI: resource: Remove "Zen" specific match and quirks") is causing keyboard problems for quite a log of AMD based laptop users, leading to many bug reports.
Revert this change for now, until we can come up with a better fix for the PS/2 IRQ trigger-type/polarity problems on some x86 laptops.

FWIW only reverting a9c4a912b7dc will also cause a regression because it did also fix the keyboard on some devices, see the links in its commit message.
