Philip Chen 20f05a3488 battery/max17055: Process negative current/temperature right
On max17055, current/temperature register values are in 2's
complement format.

Therefore we need to consider the case of negative values before
doing bitwise operation.

BUG=b:63870414
BRANCH=none
TEST=run 'battery' command and confirm the reported discharge
current looks reasonable.
