Subject[PATCH RESEND v5 5/5] arm64: dts: qcom: msm8996: Add interconnect support
Add interconnect providers for the multiple NoCs available on the platform,
and assign interconnects used by some blocks.

Signed-off-by: Yassine Oudjana <y.oudjana@protonmail.com>
---
Changes since v4:
- Add support for Aggregate 0 NoC (a0noc).
Changes since v2:
- Remove interconnect paths from CPUs since cpufreq driver doesn't support icc scaling yet.
