"icswx" is not a thing anymore, after 6ff4d3e96652 ("powerpc: Remove old=20
unused icswx based coprocessor support"). I guess NX is reusing some=20
things from it, but it would be good to get rid of the cruft and re-name
this file and and relevant names.

NX already uses this file, so I guesss that can happen after this series.

Thanks,
Nick
