mb/google/hatch/helios: Update GPIO and device tree
Based on updated schematics, change polarity of USI_INT, and add
the reset and enable GPIOs to the touchscreen ACPI node. The stop
GPIO can't be used with the current implementation of _ON, as the
way it's wired will cause power sequencing to fail.
BUG=b:137133194, b:138240502
BRANCH=none
TEST=Compiles, don't have next board rev to test with
