Add a driver to support Coresight device Trace Network On Chip (TNOC), which is an integration hierarchy integrating functionalities of TPDA and funnels. It aggregates the trace and transports to coresight trace bus.
Compared to current configuration, it has the following advantages:
- Reduce wires between subsystems.
- Continue cleaning the infrastructure.
- Reduce Data overhead by transporting raw data from source to target.

I observed a merging conflict. I would suggest you sticking to the coresight next branch for CoreSight related upstreaming. Please rebase this patch on it.
https://git.kernel.org/pub/scm/linux/kernel/git/coresight/linux.git branch: next
I also verified this patch with static checker smatch. With rebasing:
