Add an I2C connector type to match the actual connector. As Noralf Trønnes mentions in commit fc06bf1d76d6 ("drm: Add SPI connector type"), user-space should be able to cope with a connector type that does not yet understand. Tested with `modetest -M ssd1307 -c` and shows the connector as unknown-1.
