As seen on source-changes, finally I've committed changes which
add bus_space(9) support on sun3 port with existing sun68k/bus.c.

http://mail-index.netbsd.org/source-changes/2006/10/01/0003.html

There is no device drivers which have been changed to use these
bus_space(9) API yet, but this is the (late) first step to switch
sun3 port to more MI drivers like sys/dev/sun and sys/dev/vme etc.
MD bus_dma(9) backends are not implemented yet, but it should be trivial..

I'll switch homegrown todclock functions (clock and oclock) to
MI intersil7170(4) and mk48txx(4) first.
(is there anyone who can test it on 3/4xx? ;-)
