mb/google/zork: Fix active polarity of touchscreen reset GPIO in overridetree
v3.6+ of reference schematics have moved to using active low polarity for touchscreen GPIO. This change sets the default polarity in override tree accordingly to active low. To support boards from older builds, variant_touchscreen_update() already updates the polarity to active high.
