ACPI: resource: revert "Remove "Zen" specific match and quirks"

Commit a9c4a912 ("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.
