drm/i915/display: Share intel_connector_needs_modeset()
intel_connector_needs_modeset() will be used outside of
intel_display.c in a future patch so it would only be necessary to
remove the state and add the prototype to the header file.
But while at it, I simplified the arguments and moved it to a better
place intel_atomic.c.
No behavior changes intended here.
v3:
- removed digital from exported version of intel_connector_needs_modeset
- rollback connector to drm type
v4:
- Renamed new_connector_state to new_conn_state
- Going back to drm_connector_state in
intel_encoders_update_prepare/complete as we also have
intel_tv_connector_state
