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.

Also does this change need a "Fixes: ..." tag?
