Subject: [PATCH RESEND v5 0/5] interconnect: qcom: Add MSM8996 interconnect driver

This series adds a driver for interconnects on MSM8996. This fixes some rare display underflows
and provides a slight heat reduction.

Resending because some addresses in CC got mixed up.

Changes since v4:
 - Rebase on Dmitry's icc-rpm patches[1].
 - Combine SDM660 bindings into the RPM interconnect schema.
 - Clean up qcom_icc_node structs by removing unused properties, moving links to external
   arrays and using the same arrays for multiple nodes where possible.
 - Add support for Aggregate 0 NoC (a0noc).
Changes since v3:
 - Expand DEFINE_QNODE macros in msm8996.c.
 - Commonize probe function.
 - Don't rename qcom_icc_set in icc-rpmh since it's no longer needed.
 - Code style fixes.
Changes since v2:
 - Dual-license qcom,msm8996.h and move it to the dt bindings patch
 - Remove interconnect paths from CPUs since cpufreq driver doesn't support icc scaling yet.
Changes since v1:
 - Split first patch into 2 patches, one for renaming qcom_icc_set in icc-rpmh, and another
   one for the actual commonization.
 - Revert unnecessary move of include line in sdm660.c
