We keep the pflags input in mm_base_modem_grab_port() so that plugins can use other methods to gather port type hints (e.g. querying with AT commands as in Huawei/Telit or looking at sysfs properties as in HSO). For standard udev tag port type hints, it will be the base modem looking them up. Note that there is no longer any need to ignore non-flagged ports for those modems that require primary/secondary flags. They will be implicitly ignored when mm_base_modem_organize_ports() decides which ports to use, as the flagged ones are preferred over the non-flagged ones.
