event/dlb2: add v2.5 create LDB queue

event/dlb2: add v2.5 create LDB queue

Updated low level hardware functions related to configuring
load balanced queues. These functions create the queues,
as well as attach related resources required by load
balanced queues, such as sequence numbers.

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.
