I think it is better to have a pointer to the rte_bbdev/rte_device than
introducing a new ID.
Regarding performance, is_acc100 is only defined in
RTE_LIBRTE_BBDEV_DEBUG, so it should not be that critical.
Regarding that, I have hard time to understand why we need to validate
encoder/decoder parameters in ACC100 case, but not in ACC101 one. For
example, I guess having a valid mempool pointer is required in both
ACC100 and ACC101 cases.
