supply: qcom: battery: re-split FCC when ICL changes 



Currently the notifier does not respond to main psy changed events, so
changes in ICL will not schedule the status change work. Furthermore,
the status change work does not re-run the FCC splitting which is
dependent on the settled ICL.

First, add the main psy as one of the triggers for the status changed
work. Second, re-run the FCC and FV voteable elections to re-split the
FCC based on the new ICL.
