Revert "interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregate"

This reverts commit 2a691e75126a8577731366e46c5d479db5962e39, which is
causing regressions on some platforms, preventing them to boot or do a
clean reboot. This is because the above commit is sending also all the
zero bandwidth requests to turn off any resources that might be enabled
unnecessarily, but currently this may turn off interconnects that are
enabled by default, but with no consumer to keep them on.

Let's revert this for now as some platforms are not ready for such
change yet. In the future we can introduce some _ignore_unused option
that could keep also the unused resources on platforms that have only
partial interconnect support and also add .shutdown callbacks to deal
with disabling the resources in the right order.
