mb/google/sarien: Set touchpad/screen IRQs to LEVEL vs EDGE
Ensure the GPIOs themselves are configured as level triggered, as well
as the devicetree entiures. I2C-HID spec requires LEVEL trigger, and the
drivers (both Linux and Windows) work better with LEVEL vs EDGE trigger.
TEST=tested with rest of patch train
