event/dlb2: allow CQ depths up to 1024

Updated to allow overriding the default CQ depth of 32. Since there are
only 2048 DLB history list entries, increasing the CQ depth decreases
the number of available LDB ports to 2048/max_cq_depth. Resource query
will take this into account and return the correct maximum number of
LDB ports.

event/dlb2: poll HW CQ inflights before mapping queue

When attempting to link a port and queue immediately after unlinking,
the CQ inflights may not all be processed. Poll the h/w register for
outstanding inflights instead of reading once, in case the inflights
are still being processed. Also return EBUSY if the inflight
processing is not completed in a suitable amount of time.

event/dlb2: fix delayed pop test in selftest

Number of events scheduled and available for dequeue
after token pop was set to dequeue_depth-1 instead of

that all dequeue_depth number of events can be dequeued
once the last event is released.

eventdev: negate maintenance capability flag

Replace RTE_EVENT_DEV_CAP_REQUIRES_MAINT, which signaled the need
for the application to call rte_event_maintain(), with
RTE_EVENT_DEV_CAP_MAINTENANCE_FREE, which does the opposite (i.e.,
signifies that the event device does not require maintenance).

This approach is more in line with how other eventdev hardware and/or
software limitations are handled in the Eventdev API.
