net: dsa: Allow configuration of CPU & DSA port speeds/duplex
By default, DSA and CPU ports are configured to the maximum speed the switch supports. However there can be use cases where the peer devices port is slower. Allow a fixed-link property to be used with the DSA and CPU port in the device tree, and use this information to configure the port.
