it83xx: enable selecting EC's VCC
The VCC is the power source of EC's GPM0~6, will connect to 1.8v or
3.3v depended on platform design.
This change was made to ensure voltage level setting of GPM0~6 matches
the corresponded VCC level. So we can enable internal pull-up no matter
VCC is connected to 1.8v or 3.3v
BUG=b:168783892
BRANCH=none
TEST=- buildall.
- The level setting is correct on these boards:
asurada, drawcia, and reef_it8320
