[PATCH v6 1/7] bbdev: allow operation type enum for growth

[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.
