net: packetengines: remove obsolete PCI drivers

As discussed with Andrew Lunn, this patch series removes the obsolete
hamachi and yellowfin PCI drivers. Both drivers support hardware that
is over two decades old and no longer in active use.

Removing them eliminates dead code and reduces the overall maintenance
burden on the netdev subsystem.
