The chip port device index and mode bit can be obtained using the port
number.  However the mapping of port number to chip device index and
mode bit differs on Sparx5 and lan969x. Therefore ops out the function.

So for sparx5, these are identical operations, but for lan969x these
will be different? Ok.
