Craask: Setting few GPIOs to 1.8V
Few GPIO's which operate at 1.8v need to set
GPIO_VOLTAGE_1P8. This improves in EC power consumption
in S0ix mode.
For b/228222441, there is no difference on hardware
design of these GPIOs between Nivviks and Craask so
Craask also need the change CL:3702877.
BUG=none
BRANCH=none
TEST=Verified S0ix on nivviks
