document them in kernel-parameters.txt

       The new names are:
         amijoy.map=<a>,<b>
         analog.map=<type1>,<type2>,...<type16>
         db9.dev[2|3]=<parport#>,<type>
         gamecon.map[2|3]=<parport#>,<pad1>,<pad2>,...<pad5>
         turbografx.map[2|3]=<parport#>,<js1>,<js2>,...<js7>

       Also there is a tiny change to mousedev and tsdev descriptions in
       kernel-parameters, but no name changes.
