event/dlb2: add v2.5 create dir queue

Update the low level HW functions responsible for
creating directed queues. These functions configure
the depth threshold, configure queue depth, and
validate the queue creation arguments.

The logic is very similar to what was done for v2.0,
but the new combined register map for v2.0 and v2.5
uses new register names and bit names.  Additionally,
new register access macros are used so that the code
can perform the correct action, based on the hardware
version, v2.0 or v2.5.
