This is a patch to use another IRQ besides IRQ12 to fix conflicts with
i8042 - PS/2 Mouse, most commonly assigned IRQ12 by the SuperIO. It took me
this long to catch this because I usually use a USB mouse.

Good spot!

Hard coding these looks like it could work on one board and fail on another. For the i82801gx I added these to the chip's config structure, so they can be set in the device tree of the mainboard's config.lb. Maybe that's what you want here, too?
