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: optimize credit allocations using port

This commit implements the changes required for using suggested
port type hint feature. Each port uses different credit quanta
based on port type specified using port configuration flags.

Each port has separate quanta defined in dlb2_priv.h
Producer and consumer ports will need larger quanta value to reduce number
of credit calls they make. Workers can use small quanta as they mostly
work out of locally cached credits and don't request/return credits often.
