Merge branch 'icc-qdu1000' into icc-next

Add dt bindings and driver support for the Qualcomm QDU1000 and QRU1000
SoCs.

The Qualcomm Technologies, Inc. Distributed Unit 1000 and Radio Unit
1000 are new SoCs meant for enabling Open RAN solutions. See more at

+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.
