dt-bindings: arm: Add Coresight TMC Control Unit hardware

Browse source

Add binding file to specify how to define a Coresight TMC Control Unit device
in device tree.

It is responsible for controlling the data filter function based on the source
device's Trace ID for TMC ETR device. The trace data with that Trace id can get
into ETR's buffer while other trace data gets ignored.
