I fear it is not that simple. We want clockport to attach to any device
which supports it, not just to one. So I would rather try:

device  clockport
attach  clockport at clkportbus
file    dev/clockport.c

attach  ne at zbus with ne_zbus: rtl80x9, clkportbus
file    arch/amiga/dev/if_ne_zbus.c     ne_zbus needs-flag

device  mainbus: clkportbus

Don't know if the syntax is correct, but maybe you get the idea?
