drm/i915: Update atomic state when removing mst connector, v3.
Fully remove the MST connector from the atomic state, and remove the
early returns in check_*_state for MST connectors.
With atomic the state can be made consistent all the time.
Thanks to Sivakumar Thulasimani for the idea of using
drm_atomic_helper_set_config.
Changes since v1:
- Remove the MST check in intel_connector_check_state too.
Changes since v2:
- Use drm_atomic_helper_set_config.
