UPSTREAM: coresight: tmc-etr: Introduce the notion of IDR to ETR devices

(Upstream commit c5ff734462b1d32f793db717ef222cd05e6232d5).

In CPU-wide scenarios with an N:1 source/sink topology, sources share
the same sink.  In order to reuse the same sink for all sources an
IDR is needed to archive events that have already been accounted for.
