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.
