Added device status information, so that the PMD can expose
information related to the underlying accelerator device status.
Minor order change in structure to fit into padding hole.

I don't have a strong opinion on this, but I think NOT_SUPPORTED
should be a special value. If you want to keep 0 value for NOSTATUS,
maybe you could
do:
enum rte_bbdev_device_status {
RTE_BBDEV_DEV_NOT_SUPPORTED = -1, /**< Device status is not
supported
on the PMD */
RTE_BBDEV_DEV_NOSTATUS = 0, /**< Nothing being reported
*/
RTE_BBDEV_DEV_RESET, /**< Device in reset and un-
configured
state */
...
