Subject: [PATCH] ACPI: resource: Do IRQ override on MECHREVO Yilong15 Series GM5HG0A

From: MuelNova <n@....moe>

MECHREVO Yilong15 Serie has a DSDT table that describes IRQ 1 as ActiveLow
while the kernel is overriding it to Edge_High. This prevents the internal
keyboard from working. This patch prevents this issue by adding this laptop
to the override table that prevents the kernel from overriding this IRQ
