Add a list of I2C ports
This cleans up I2C init and debug commands across boards.
Signed-off-by: Randall Spangler <rspangler@chromium.org>
BUG=none
TEST=on link and bds:
i2cscan
lightbar run
powerbtn (to power on system)
temps (to read i2c temp sensors)
battery (to read battery)
charger (to read charger)
