mb/google/zork: Add GPIO_144 in touchscreen power on/off sequence
Add GPIO_144 setting to fix touchscreen function not work.
1. Modify reset pin to stop gpio delay to 200ms.
2. Reset GPIO off delay set to 1ms.
3. Add GPIO_144 as stop GPIO.
4. Stop GPIO off delay set to 1ms.
5. Set disable_gpio_export_in_crs = 1.
