[src/trunk]: src/sys/arch/luna68k/dev Misc cleanup of sio drivers.
details: https://anonhg.NetBSD.org/src/rev/99c06b167f5a
branches: trunk
changeset: 326554:99c06b167f5a
user: tsutsui <tsutsui%NetBSD.org@localhost>

description:
Misc cleanup of sio drivers.
- register softc of child devices as an argument of the sio interrupt
handler to avoid device_lookup_private() calls on every interrupt
- change type of sc_reg from (void *) to (struct sioreg *)
to avoid weird address offset calculations with redundant casts
- rename struct sio_softc members for consistency
- use a channel number passed via sio_attach_args in lunaws_attach()
No functional chnages. Tested on LUNA.
