Subject: [PATCH v2 1/3] dt-bindings: interconnect: Add schema for SM8550
Add dedicated schema file for SM8500. This allows better constraining
of reg property, depending on the type of the NOC node. Also allows
better constraining of the clocks property. All of the above while
keeping the file itself comprehensible.

+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.
