[PATCH] net: ethernet: ti: cpsw: disable PTPv1 hw timestamping advertisement

The TI CPTS does not natively support PTPv1, only PTPv2. But, as it happens, the CPTS can provide HW timestamp for PTPv1 Sync messages, because CPTS HW parser looks for PTP messageType id in PTP message octet 0 which value is 0 for PTPv1. As result, CPTS HW can detect Sync messages for PTPv1 and PT
