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.

This patch breaks reboot for me on sc7180 Lazor
FWIW, it prevents at least SM8150 from booting (need to check my other
boards as well), because its no longer okay to have the interconnect
providers defined without having all client paths specified.
