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.
