Log Message:
Add a new MI attribute, pckbc_machdep_cnattach, and change pckbc_cnattach()
to only call pckbc_machdep_cnattach() if this is present.  This allows
pckbc_machdep_cnattach() to be omitted entirely on most ports, where it only
returns ENXIO anyway.

The devices with this attribute at the moment are pc(4) on i386 and bebox, and
pckbc on sparc, where pckbc_machdep_cnattach() mysteriously returns 0 rather
than ENXIO.
