WIP 100BASE-TX PHY

Sean Anderson b351beb9a0 Add hub ... This adds a basic hub wrapper module which incorperates the core introduced in b68e131 ("Add a basic hub"). For each port, it instantiates a phy (itself using a phy_internal wrapper) and an elastic buffer. A WISHBONE parameter is used to control whether to instantiate a wishbone interface. When disabled, we just respond to any request with err. I've ommitted a separate testbench for phy_internal, since it is much easier to create a smoke test using the hub interface.
