OpenCellular/test/sbs_charging.c
Louis Yung-Chieh Lo 5a4b239981 rename power_state* to charge_state* 
Those are actually charge state, not power state. Rename the misleading
names.

BUG=chrome-os-partner:24832
BRANCH=link,falco,samus,rambi,peppy,spring,pit,snow
TEST=build only because no name conflicts.
