Subject: [PATCH 3/7] dt-bindings: interconnect: qcom: Fix and separate out
 MSM8916

Separate out MSM8916 icc bindings and fix the clocks description by
removing the wrong internal RPM bus clock representation that we've
been carrying for years.

Replace the example in qcom,rpm.yaml with MSM8939 to keep it relevant
to the file.
