Previously, the initiators were implicitly coupled to the responses of
the memory, calculating each new initiator clock relatively based on the
time of the BEGIN_RESP phase. This lead to an implicit coupling as
same rounding error of the initiator clock to the memory clock was
applied each time again.
Now, initiators are in itself self-clocked and only send requests based
on backpressure.
