drm/connector: Set DDC pointer in drmm_connector_init

Commit 35a3b82 ("drm/connector: Introduce drmm_connector_init") introduced the function drmm_connector_init() with a parameter for an optional ddc pointer to the i2c controller used to access the DDC bus. However, the underlying call to __drm_connector_init() was always setting it to NULL instead of passing the ddc argument around. This resulted in unexpected null pointer dereference on platforms expecting to get a DDC controller.
