mb/google/guybrush: Fix trackpad SCI config

Trackpad GPIO configuration does not align with the IRQ configuration
in the devicetree. Configure the trackpad GPIO to generate SCI on
falling edge.

BUG=None
TEST=Build and boot to OS in Nipperkin. Ensure the trackpad is
functional. Suspend the device and wake it using trackpad. Perform
suspend/resume sequence for 100 iterations.
