mb/google/hatch/variants: Increase touchscreen reset delay to 120ms
During boot sequence sometime touchscreen reset keeps failing. Also, kernel dmesg shows "dmesg:i2c_hid i2c-GDIX0000:00: failed to reset device" message. This adds around 4 more seconds to the boot sequence. Setting the appropriate delay of 120ms between enable and reset for Goodix Touchscreen helps to synchronize and address this failure. This value is 120 ms as per Goodix Spec.
