Subject: [PATCH v2 2/2] ACPI: skip IRQ1 override on Redmi Book Pro 15 2022

From: Tighe Donnelly <tighe.donnelly@...tonmail.com>

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.
