coresight: add coresight Trace Network On Chip driver
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:
1. Reduce wires between subsystems.
2. Continue cleaning the infrastructure.
3. Reduce Data overhead by transporting raw data from source to target.
