Certain chips have I2C ports mapped to the same controller. In this case, it's necessary to lock out access to the controller during use. This configuration can be supported by adding CONFIG_I2C_MULTI_PORT_CONTROLLER, which can be defined at the chip level, along with an API function to map port index to controller index. BUG=chrome-os-partner:38335,chrome-os-partner:38945 TEST=Manual with subsequent commit. Verify that i2cscan is functional on strago.
