[rainbow public-key-only device]

Opencrypto drivers for crypto hardware just register themselves as
implementing transforms, from a predefined set, for whichver tranforms

If the operations provided by the Rainbow hardware match the
alread-defined asymmetric (public-key) ops: sure, no problem, a SMOP.
