net: dsa: lantiq_gswip: set link parameters also for CPU port

Browse Source 
On standalone switch ICs the link parameters of the CPU port need to
be setup just like user ports. The destinction in the driver to not
carry out link parameter setup for the CPU port does make sense for
in-SoC switches on which the CPU port is internally connected to the
SoC's Ethernet MAC.
Set link parameters also for the CPU port unless it is an internal
interface. Note that the internal TP PHYs anyway cannot be used as
CPU ports, hence it doesn't matter that they are now also covered by
that condition.
