charge_manager: Minimize log spew
Previously, we tried to minimize log spew by keeping track of previous
log entries and not writing new entries in some cases. Instead, we can
write a log on the following events only:
1. A port becomes active or
2. A port becomes inactive or
3. The active charge port power limit changes or
4. Any supplier change on an inactive port
Also, make charge_manager_save_log a non-static charge manager API
function, so that other modules can record a log, if they have reason to
believe a port has changed outside of a charge manager change.
BUG=chrome-os-partner:33248
TEST=Manual on Samus. Make various power actions and observe logging.
BRANCH=Samus
