Madoo: Fix main board charger can't wake from hibernate
In madoo's design, there is a protection IC between USB
connector and TCPC. When EC is hibernate, the CC lines will
be disconnected, which cause the result that TCPC can't
detect AC power and Chromebook won't wake the system.
Enalbing ADC for all modes by setting 0x4C bit 0 to 1 (to be
more precise is that we don't clear bit 0 during hibernation)
can prevent issue mention above.
BUG=b:174971576
BRANCH=dedede
TEST=flash code and make sure ac in can wake system from hibernation
