Add new charge_ramp module which works with charge_manager to slowly increase input current limit in order to find the optimal charging current. To do this it looks for either VBUS drooping too low or for the charger to over-current. BUG=chrome-os-partner:34946 BRANCH=samus TEST=tested with a variety of BC1.2 chargers, type-C only chargers, and PD chargers to make sure we always stabilize charging at an appropriate current limit.
