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. BUG=chrome-os-partner:28585 BRANCH=none 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 line. Tested on plankton and zinger to make sure PD works as expected.
