====================
net: dsa: lantiq: add support for Intel GSW150

The Intel GSW150 Ethernet Switch (aka. Lantiq PEB7084) is the predecessor of
MaxLinear's GSW1xx series of switches. It shares most features, but has a
slightly different port layout and different MII interfaces.
Adding support for this switch to the mxl-gsw1xx driver is quite trivial.
