Subject: [PATCH v2 2/4] interconnect: Always call pre_aggregate before aggregate

The pre_aggregate callback isn't called in all cases before calling
aggregate. Add the missing calls so providers can rely on consistent
framework behavior.

Fixes: d3703b3e255f ("interconnect: Aggregate before setting initial bandwidth")
