blipper: disable charger ADC function at Z-state
In order to reduce the power consumption of Z-state, we need
disable charger ADC function at Z-state, and we use HW solution
to solve AC cannot wake up Z-state issue.
BUG=b:186717219
BRANCH=dedede
TEST=EE verify the power consumption ok,and AC can wakeup Z-state
at rework duts
