interconnect patches for 5.4

Here are the interconnect driver updates for the 5.4-rc1 merge window.

- New feature is the path tagging support that helps with grouping and
aggregating the bandwidth requests into separate buckets based on a tag.
- The first user of the path tagging is the Qualcomm sdm845 driver that
now implements support for wake/sleep sets. This allows consumer drivers
to express their bandwidth needs for the different CPU power states.
- New interconnect driver for the qcs404 platforms and a driver that
communicates bandwidth requests with remote processor over shared memory.
- Cleanups and fixes.
