Subject: [PATCH v2 5/7] dt-bindings: interconnect: qcom: Fix and separate
out MSM8939
Separate out MSM8939 icc bindings from the common file and fix the
clocks description by removing the wrong internal RPM bus clock
representation that we've been carrying for years.
This was the final one, so also retire the shared file.
