interconnect fixes for v5.10

This contains one core fix and a few driver fixes.
- Fix the core to perform also aggregation when setting the initial
  bandwidth with sync_state.
- Fixes in some drivers to make sure the correct sequence is used for
  initialization when we use sync_state.
- Fix in the sdm845 driver to prevent a board hang that was hit when
  bandwidth scaling for display and multimedia was enabled.
