Chautru, Nicolas Sept. 22, 2022, 5:45 p.m. UTC 
  From: Nicolas Chautru <nicolas.chautru@intel.com>

Updating the enum for rte_bbdev_op_type
to allow to keep ABI compatible for enum insertion
while adding padded maximum value for array need.
Removing RTE_BBDEV_OP_TYPE_COUNT and instead exposing
RTE_BBDEV_OP_TYPE_PADDED_MAX.
