dsa: marvell: Add support for mv88e6071 and 6020  switches

After the commit (SHA1: 7e9517375a14f44ee830ca1c3278076dd65fcc8f);
"net: dsa: mv88e6xxx: fix max_mtu of 1492 on 6165, 6191, 6220, 6250, 6290" the
error when mv88e6020 or mv88e6071 is used is not present anymore.

As a result patches for adding max frame size are not required to provide
working setup with aforementioned switches.
