"icswx" is not a thing anymore, after 6ff4d3e96652 ("powerpc: Remove old
unused icswx based coprocessor support"). I guess NX is reusing some
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,
