Subject[PATCH v2 1/2] ACPI: skip IRQ1 override on Lenovo ThinkBook 14G4+ ARA
Date
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.

Change since v1:
Match DMI DMI_PRODUCT_NAME for ThinkBook because the board name
is used for other completely different Lenovo laptops.
