[dpdk-dev] [PATCH 14/20 v2] bus/fslmc: add callback per queue to enable

[Nipun Gupta]

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.
