interconnect changes for 6.18

This pull request contains the interconnect changes for the 6.18-rc1
merge window. It contains new driver and a minor core cleanup.

Core change:
- Use device_match_of_node() instead of open coding it

Driver changes:
- Add new driver for the Qualcomm Glymur SoC
- Enable OSM L3 support for the QCS615 SoC

Signed-off-by: Georgi Djakov <djakov@kernel.org>

+description: |
+  RPMh interconnect providers support system bandwidth requirements through
+  RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
+  able to communicate with the BCM through the Resource State Coordinator (RSC)
+  associated with each execution environment. Provider nodes must point to at
+  least one RPMh device child node pertaining to their RSC and each provider
+  can map to multiple RPMh resources.
