grunt: Turn PP1800_SENSOR off in S5
Disable sensor power (lid accel, gyro) in G3+S5. Enable
it in S3+S0. We want it on in S3 for calculating the lid
angle (needed on convertibles to disable resume from
keyboard in tablet mode).
BUG=b:72741289
BRANCH=none
TEST=GPIO_EN_PP1800_SENSOR =0 in G3+S5 and =1 in S3+S0
