dt-bindings: arm: Add device Trace Network On Chip definition

Add a new coresight-tnoc.yaml file to describe the bindings required to
define Trace Network On Chip (TNOC) in device trees. TNOC is an
integration hierarchy which is a hardware component that integrates the
functionalities of TPDA and funnels. It collects trace form subsystems
and transfers to coresight sink.
