Subject: [PATCH] ACPI: resource: Add IRQ override for MECHREV Jiaolong17KS

Fix a regression introduced by commit 9946e39fe8d0 ("ACPI: resource: skip
IRQ override on AMD Zen platforms") on MECHREV Jiaolong17KS, which
causes the built-in keyboard to not work. This restores the functionality
by adding an IRQ override.

I have personally tested this on the 17" model but I'm not sure if this
issue is present on the 16 model.

Fixes: 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen platforms")
