Shawn Nematbakhsh 94f2bc0740 charge_manager: Pass uncapped / max current to current limit callback 
charge_manager may request a charge current limit less than the
capability of the supply in certain cases (eg. during PD voltage
transition, to make an effort to comply with reduced load spec).
Depending on the battery / system state, setting a reduced charge
current limit may result in brownout.

Pass the uncapped / max negotiated current to board_set_charge_limit()
so that boards may use it instead of the requested limit in such
circumstances.

BUG=chrome-os-partner:56139
BRANCH=gru
TEST=Manual on kevin with subsequent commit, boot system with zinger +
low-charge battery, verify devices powers up to OS without brownout.
