mb/google/fatcat/var/fatcat: Change touchpad interrupt to edge trigger

This change modifies the touchpad interrupt configuration to use
edge-triggered interrupts instead of level-triggered interrupts.

This is necessary to ensure that the touchpad interrupt is properly
detected by the AP w/o seeing interrupt flood.

BUG=b:376019577
TEST=Verified that the touchpad works smoothly with this change.
