Log Message:
A bit of clock rototill.  It's safer to detect things known by the
residual with the pnpbus probes, than it is to do it with raw isa probes,
so I've replaced the isa mkclock and mcclock code with a pnpbus attachment.

While writing the mkclock code, I realized that on motorola prep machines
the mkclock uses the same port range as the nvram part. (it's actually
the same chip/part).  This was causing the nvram not to work on those
machines.  Now the nvram code will recognize this, and wire up the
mkclock as well.  The mkclock probe is just a stub probe used to
pre-detect the fact that this is one of those machines.
