Strip down the support for topology enums. It
can be replaced with simple hw count checks.
Can you remove the enum entirely? A quick scan seems like it might be
possible,
it seems like it's only used in topology_def to pass to reservations
and
it's
only used in reservations for log messages. Ofc, I might be missing
some
usage a
little more buried...
