mb/google/sarien: Fix s5 touchscreen power leakage
Leakage power is observed from TOUCH_SCREEN_PD# (GPP_E7 which is connected
to RESET pin of Wacom controller) during S5.
To avoid leakage power, GPP_E7 needs to be turned off before S5 entry.
BUG=b:129899315
TEST=Measure leakage power in S5 from both Arcada and Sarien
