There isn't a connector type for display controllers accesed through I2C, most drivers use DRM_MODE_CONNECTOR_Unknown or DRM_MODE_CONNECTOR_VIRTUAL.
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.
I had expected unknown-21??
As you pointed out in patch 3/4, I forgot to change DRM_MODE_CONNECTOR_Unknown to DRM_MODE_CONNECTOR_I2C after adding this patch...
