Add a driver for the MSM8996 NoCs. This chip is similar to SDM660 where
some busses are controlled by RPM, while others directly by the AP with
writes to QoS registers
Thank you for working on this!

Changes since v4:
- Rebase on Dmitry's icc-rpm patches.
- 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.
- Code style fixes.

I have fixed the above issue and applied patches 1-4.
Thanks,
