description:
Provisionally return to declaring midi_cd unconditionally.

Apparently this breaks compiling some kernels, although how they ever
managed to link if midi_cd is not declared in ioconf.h, and therefore
presumably not defined in ioconf.c, is beyond me.

Maybe someone who knows how sequencer is supposed to work, and/or
someone who knows how arm kernels are linked, can figure this out...
