This reverts commit7458bd540f("net: dsa: bcm_sf2: Also configure Port 5 for 2Gb/sec on 7278") as it causes advanced congestion buffering issues with 7278 switch devices when using their internal Giabit PHY. While this is being debugged, continue with conservative defaults that work and do not cause packet loss.
