drm/mgag200: Set .detect_ctx() and enable connector polling

Set .detect_ctx() in struct drm_connector_helper_funcs to the
common helper drm_connector_helper_detect_from_ddc() and enable
polling for the connector. Mgag200 will now test for the monitor's
presence by probing the DDC in regular intervals.
