Changes since 1.17: +3 -3 lines

Tidy up a little, the way that midi attachment code works

- change midi_attach() to omit the 'parent' arg (there are
  only two callers of this and it is not used)

- change midisyn_attach() to midisyn_init(), so not needing a midi_softc,
  and fix the midi_pcppi driver to set hw_if and hw_hdl directly in
  its midi_softc before calling midi_attach()

- add a device_t to opl_softc structure, change opl drivers to store
  the device 'self' in opl_softc and fix opl_attach() to use this
  opl_softc->dev field directly rather than a field in an otherwise
  unused midi_softc

- remove unnecessary midi_softc from opl and cms drivers (child device
  provides that)
