This series adds interconnect support for the various NoCs found on
sm6350.
A more special modification is allowing child NoC devices, like done for
rpm-based qcm2290 which was already merged, but now for rpmh-based
interconnect.

Add all the different NoC providers that are found in SM6350 and
populate different nodes that use the interconnect properties.

Newer SoCs seem to have switched to using #interconnect-cells = <2>;
Is this something that should be done for all new implementations as
well? The 'tag' in the second cell seems to be 0 for all cases in
mainline except CPU.

Yes, it's recommended to use #interconnect-cells = <2> (if you care about
power management). This is to support different bandwidth configurations
that are toggled by RPMh, depending on the power state of the CPU.
