Subject: [PATCH v2 1/7] 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.

- able to communicate with the BCM through the Resource State Coordinator (RSC)
