fixed_phy_register returns a struct phy_device pointer with a held

  pointer via PTR_ERR_OR_ZERO, and the phy_device's fwnode is not set, so
  of_phy_deregister_fixed_link cannot find the device via
  bus_find_device_by_fwnode to clean it up. This permanently leaks the
  phy_device and its device_node reference.

Store the returned phy_device pointer and set dev->fwnode so the
  deregister path can properly locate and clean it up.
