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_PRODUCT_NAME for ThinkBook because the board name
 is used for other completely different Lenovo laptops.

Change since v2:
 fix alphabetical order in skip_override_table
