[PATCH v4 5/5] arm64: dts: qcom: msm8996: Add interconnect support

[Yassine Oudjana <y.oudjana@xxxxxxxxxxxxxx>]

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@xxxxxxxxxxxxxx>
---
Changes since v2:
 - Remove interconnect paths from CPUs since cpufreq driver doesn't support icc scaling yet.
