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.

Like Samus, the battery can be placed into a disconnect state. This CL
implements the necessary function to determine if it is so and kick it
out of this state when possible.
BUG=chrome-os-partner:30633
TEST=Put a battery in this state. Plug in AC. Verify the battery is
revived.

Only one EC was an i2c slave, samus_pd.
Now we have 2 more, ryu and ryu_sh (sensor hub).

This is a straightforward conversion of existing tables
into X-Macro style definitions for the GPIO alternate
functions. This change in itself, is not particularly
powerful, but having all GPIO settings in a single file
makes a board easier to understand.
