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).

Remove code for preventing PD negotiation until the battery
is at some minimum SOC. This was originally necessary because
transitioning voltages would cause the source voltage to go
briefly to 0V, which would kill power to the system unless
the battery was at some minimum level of charge. But, that
isn't true anymore. It is safe to transition up or down in
voltage and the source voltage should never drop to 0V.

Previously if you were working on a single board you had to add BOARD=
to all of your make command lines. Now if you are in a board directory
you can just use "make", or "make clean", or any other top level make
command.
This commit also adds support for a top level "make flash" command that
can be used from the board directories as well. This command uses
openocd and requires that the board provides an openocd-flash.cfg file.

Adds dual USB-PD port support for samus. Both ports are in dual-role
and can perform either role.
Both ports work fine when only one of the ports is in use. But,
still having problems with PD errors on the lower priority port (port
0). If you have a charger plugged into port 0, and a type-C USB dongle
plugged into port 1, then port 1 has higher priority, and in the
SRC_DISCONNECTED state, every 1.5 seconds when it sends source cap
packet, we occasionally drop pings on port 0, which results in a
lot of start/stop charging.

TEST=Tested on samus to make sure both ports work when I
plug in a charger and a type-C USB dongle with a pull-down on the CC
