net: dsa: mv88e6xxx: Add support for ethernet switch 88E6141

The Marvell 88E6341 device is single-chip, 6-port Ethernet switch with
four integrated 10/100/1000Mbps Ethernet transceivers and one high speed
SerDes interfaces.

It belongs to the Topaz family and unlike the 88E6341 it does not have
a TCAM.
