mainboard/google/soraka: pull high TOUCHSCREEN_STOP_L pin
After updating to Wacom Firmware version 501, touchscreen can't work.
Wacom FW (ver. 501) enables STOP function.
STOP Pin:
High: Normal Operation
Low: Stop Scanning
So pull TOUCHSCREEN_STOP_L high
BUG=b:37007801, b:37265219
BRANCH=none
TEST=manual testing on Soraka board and touchscreen works at boot
and after suspend/resume.
