Only ask the charger for current steps it can supply
This reduces oscillations in the charging algorithm. This change also adds
more debug output so it's easier to see what the charging state machine is
doing.
BUG=chrome-os-partner:9572
BRANCH=link
TEST=discharge battery; charge battery; note infrequent but useful debug output
