event/dlb2: add v2.5 create dir port

Update the low level HW functions responsible for
creating directed ports. These functions create the
producer port (PP), configure the consumer queue (CQ),
configure queue depth, and validate the port 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.
