net: phy: Represent PHY-less SFP modules with phy_port

Now that the SFP bus infrastructure notifies when PHY-less modules are
connected, we can create a phy_port to represent it. Instead of letting
the SFP subsystem handle that, the Bus' upstream is in charge of
maintaining that phy_port and register it to the topology, as the
upstream (in this case a phy device) is directly interacting with the
underlying net_device.

Add a phy_caps helper to get the achievable modes on this module based
on what the phy_port representing the bus supports.
