Subject: [PATCH v2] ACPI: resource: Add LG 16T90SP to
 irq1_level_low_skip_override[]

The LG Gram Pro 16 2-in-1 (2024) the 16T90SP has its keybopard IRQ (1)
described as ActiveLow in the DSDT, which the kernel overrides to EdgeHigh
which breaks the keyboard.

Add the 16T90SP to the irq1_level_low_skip_override[] quirk table to fix
this.

Note that I do not have the relevant hardware since I'm sending in this
quirk at the request of someone else.

Changes in v2:
- fix the double initialization warning reported by the kernel test
  robot, which accidentially overwrote another quirk
- Link to v1: https://lore.kernel.org/r/20241016-lg-gram-pro-keyboard-v1-1-34306123102f@heusel.eu
