charge_state_v2: Add charge_set_output_current_limit function
This function sets up and enables "OTG" mode on the charger chip
(i.e. use the charger to provide power from the battery).
It also records the output current in curr.output_current, to
make sure that the charger loop is aware that current is provided
externally.
We also add a CONFIG_CHARGER_OTG to remove these functions on
boards that do not require it.
BRANCH=none
BUG=b:65697962
TEST=On wand, when discharging, battery status is updated every
5 seconds (and not every 60 seconds).
