interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregate
We're only adding BCMs to the commit list in aggregate(), but there are cases where pre_aggregate() is called without subsequently calling aggregate(). In particular, in icc_sync_state() when a node with initial BW has zero requests. Since BCMs aren't added to the commit list in these cases, we don't actually send the zero BW request to HW. So the resources remain on unnecessarily. Add BCMs to the commit list in pre_aggregate() instead, which is always called even when there are no requests.
