Constrain charging voltage to values chargers can provide.
BUG=chrome-os-partner:20863
BRANCH=falco,peppy,slippy,wolf
TEST=Manual. On Peppy, there should no longer be "Charging
Voltage" messages every second on the EC console. On other platforms
verify that V_Batt reported by the 'charger' command is divisible
by 16.
