Trickle charging state and minor bugs fix
Adding trickle charging mode to precharge batteries with
voltage lower than minimal design value. This CL adds
control to charger voltage to track battery input current
change.
To prevent battery from deeply discharging, this CL preserves
3% of the design capacity.
Minor bug fixes include error state check and charger control
logic.

BUG=chrome-os-partner:8660,8661
TEST=manual
Plug AC power, the power adapter led should be
'yellow'. On the EC serial console, type 'battery'
and 'charger' commands.
Battery input current should staid close to its
desired current.
A deeply discharged battery (5.5V) should be revived to
a healthy state after 30 minutes ~ 4 hours.
