Eliminate the default address map member of address_space_config (nw)
Since all device address maps are now class methods defined in ordinary C++, default RAM maps can be provided more simply with an explicit has_configured_map check in an internal map definition. A number of default address maps that probably weren't meant to be overridden have also been changed to ordinary internal maps.
