[PATCH v2 1/7] dt-bindings: interconnect: qcom: Introduce qcom,rpm-common

[Konrad Dybcio <konrad.dybcio@linaro.org>]

The current RPM interconnect bindings are messy. Start cleaning them
up with a common include.

+description:
+  RPM interconnect providers support for managing system bandwidth requirements
+  through manual requests based on either predefined values or as indicated by
+  the bus monitor hardware. Each provider node represents a NoC bus master,
