To avoid issues where adapter would drive against OTG of lid or
base, and to make sure that we do not over-current the adapter,
we disconnect the base/lid power transfer whenever a new
adapter is connected.
We reenable power transfer as needed.
We also separate out base current control as a new function,
that allows us to record the previous base current only when
the base charge control command is successful, and ignore
errors until the base is responsive for the first time.
Finally, we make sure that
charge_allocate_input_current_limit is only called from a
single location in charger_task.
BRANCH=none
BUG=b:71881017
TEST=Plug/unplug base, reset lux EC, connect charger.
Base is detected, power allocation works as expected.
