dt-bindings: interconnect: single yaml file for RPMh interconnect drivers 

These two bindings are almost identical, so combine them into one. This
will make it easier to add the sm8150 and sm8250 interconnect bindings.

SC7180 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.
