Expose the idfilter* registers of the programmable replicator.

Is this for SoC600 only? If so we need to make sure these are not visible when
operating an SoC400 replicator. Otherwise simply disregard my statement.

No, this is for the existing dynamic replicator, which is also compatible with the
one in SoC-600. In the future, we may be able to support multiple trace sessions
(i.e, distinct source-sink pairs using a shared dynamic replicator to filter the
data based on the trace-id). Right now we simple switch off the other side of the
replicator, when we enable the port connected to the sink.

I found these useful while debugging trace generation issue on one of the
platforms.
