Add driver for the Qualcomm interconnect buses found in MSM8939 based
platforms. The topology consists of four NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each

MSM8916 and QCS404 bindings are almost identical, so combine them into one.
This will make it easier to add interconnect bindings for more SoC with RPM.

This patch set split shared RPM based interconnect operation code and add
support to MSM8939 interconnect.
Changes vs V1:
- Rebase to latest icc code.
- Remove unnecessary comment and info.
- Fix some format issues.

Thanks for reminde
Add MSM8939 RPM power domains and associated document. This is based on
Stephan's patch set to reuse max state definition:
https://lore.kernel.org/linux-arm-msm/20200916104135.25085-1-step...@gerhold.net/
Changes vs v2:
- fix max power domain state value.
- trim code layout.

Add the shared modemcx/cx/mx power-domains found on MSM8939.
