    This patch adds support for a DSA mock-up driver which essentially does
    the following:
    
    - registers/unregisters 4 fixed PHYs to the slave network devices
    - uses eth0 (configurable) as the master netdev
    - registers the switch as a fixed MDIO device against the fixed MDIO bus
      at address 31
    - includes dynamic debug prints for dsa_switch_ops functions that can be
      enabled to get call traces
    
    This is a good way to test modular builds as well as exercise the DSA
    APIs without requiring access to real hardware. This does not test the
    data-path, although this could be added later on.
