mb/google/brya/var/xol: Change touchpad I2C interrupt type to GPIO_INT

If user continues to use the touchpad for over 3 minutes on Xol, the
pointer movement is stuttering.

Touchpad I2C transaction should appear during the interrupt signal level
is low, but we could see some more I2C transaction after the interrupt
signal(GPP_F14) went to high.

We found experimentally that changing the interrupt type to GPIO_INT
from APIC_IRQ improved this issue. We are still investigating, would
like to apply this change first for Xol's dogfooding.

BUG=b:350609957
BRANCH=brya
TEST=built and verified there's no stuttering issue on touchpad movement
