interconnect changes for 5.10

Here are the interconnect changes for the 5.10-rc1 merge window
consisting of core changes, new drivers and cleanups.

Core changes:
 - New bulk API helpers for managing multiple interconnect paths.
 - New xlate_extended() interface for parsing additional data from DT.
 - Support for sync_state().

Driver changes:
 - New drivers for SM8150 and SM8250 platforms.
 - New drivers for the Qualcomm OSM and EPSS hardware blocks.
 - Per-BCM scaling factor support.
 - Misc cleanups.
