When the Felix driver would probe the ports and verify functionality, it would fail if it hit single port mode that wasn't supported by the driver. The initial case for the VSC7512 driver will have physical ports that exist, but aren't supported by the driver implementation. Add the OCELOT_PORT_MODE_NONE macro to handle this scenario, and allow the Felix driver to continue with all the ports that are currently functional.
