Subject: [PATCH v3 6/9] arm64: dts: qcom: msm8939: Drop RPM bus clocks

Some nodes are abusingly referencing some of the internal bus clocks,
that were recently removed in Linux (because the original implementation
did not make much sense), managing them as if they were the only devices
on an NoC bus.

These clocks are now handled from within the icc framework and are
no longer registered from within the CCF. Remove them.
