Alec Berg 91bbfb780c samus: set BQ voltage to battery voltage when AC disconnected

Set charge state machine voltage to just above the battery voltage
when AC is disconnected. Also send new current before sending new
voltage to charger when there is a change. These changes reduce
input current spikes caused by current inrush into the battery and
thereby decrease chance of overcurrenting power supply on connect.

BUG=chrome-os-partner:33862
BRANCH=samus
TEST=load onto samus instrumented with input current probe. when
AC is attached note that initial current spike is much lower with
this change.
