mb/google/zork: Fix active polarity of REPORT_EN pin in overridetree
GPIO_144 is REPORT_EN pin for the touchscreen controller where 1 means
enable operation and 0 means stop operation. Override tree exposes
this pin as stop GPIO. Thus, it needs to be configured as active low
i.e. 0 = active (stop), 1 = inactive (enable report).
