Battery: Apply full factor to full capacity
This change introduces CONFIG_BATT_HOST_FULL_FACTOR. If it's 100,
meaning no compensation, we multiply full capacity by
CONFIG_BATT_FULL_FACTOR. This makes the rest of the system see
consistent charge percentage behavior.

BRANCH=none
TEST=Verify display percentages printed by EC and power_supply_info
move up synchronously on charge and turns to full at the same time.
