s2650: I/O modernization
- Replace fake S2650_SENSE_PORT address with line read callback (set_input_line should also work). There are still some doubts regarding whether VBLANK should be inverted in various drivers. - Replace fake S2650_CTRL_PORT and S2650_DATA_PORT addresses with... well, these aren't dedicated parallel ports, so they actually haven't gone away. They have, however, been moved to a new 1-bit address space, since the ports share the main data bus and are distinguished from each other by an address line.
