In most cases, it's more useful to just use the intel_dp struct since it indicates whether or not we're dealing with an MST device, along with being able to easily trace the intel_dp struct back to it's respective connector (if there is any). So, move the modeset_retry_work function out of the intel_connector struct and into intel_dp.
