The IRQ is described as (Edge, ActiveLow, Shared, ) in ACPI DSDT and
it's correct. The override makes the keyboard interrupt polarity
inverted, resulting in non-functional keyboard.
Add an entry for skipping the override.

It seems that this issue present on several other Ryzen 6000 laptops.
The dmi table is named genericly because I'm expecting this list to
get filled with laptops from other vendors.
