exidy.cpp: Got rid of duplicate coin inputs.

Browse Source 
Partially addresses GitHub #9757.  Coin 2 doesn't work for targ and
spectar, but that isn't a regression (it was already broken, not sure if
error in schematics, game bug, or emulation issue is to blame).  DIP
switches and locations are still a bit of a mess, too.
