cxl: Preserve the CDAT access_coordinate for an endpoint

Browse Source 
Keep the access_coordinate from the CDAT tables for region perf
calculations. The region perf calculation requires all participating
endpoints to have arrived in order to determine if there are limitations
of bandwidth data due to shared uplink.
