Set input current limit based on the max current from the
PD negotiation. For samus, this information is passed to
the EC as a host command. For ryu, the max current is set
directly following a negotiation.
CONFIG_CHARGER_INPUT_CURRENT is now just the default limit,
but after a successful PD negotiation, the limit can be
raised.
Note, for now the input current limit for samus is set to
2/3 of the value negotiated for. This is due to hardware
problems measuring input current on p2b boards.
BUG=chrome-os-partner:28532, chrome-os-partner:24461
BRANCH=none
TEST=tested on a samus. Verified input current limit using
"charger" console command from EC. Input current limit
after a reboot is 512. When zinger is plugged in, it jumps
to the appropriate value (currently 1280mA), and when
the negotiation is changed using the "pd 0 dev 5" command
on the PD console, the input current limit is adjusted to
match (2000mA).
