seattle.cpp and vegas.cpp: Clean House (nw)

[Hydreigon223]

All unnecessary inputs are removed from all respective games without problems. I decided to remove "IMPERFECT_SOUND" from the NBA Showtime games because those games used a standard Vegas SIO board.

Also changed the monitor resolution dip switch setting to reflect factory defaults. warfa originally came shipped with a standard res monitor and roadburn with a VGA res monitor.

We usually provide all inputs a board supports (e.g. shown in service mode), even if games don’t use them.

[Hydreigon223]

Except most of these games don't show the unused inputs in service mode (Road Burners for example). Also look at naomi.cpp as game specific inputs for this driver end up removing most of the unused inputs. Would you think it's okay to leave unused inputs as is in hotd2? I personally think it isn't.
