Introduction of Coresight Dummy subunit
The Coresight Dummy subunit is for Coresight Dummy component, there are some
specific Coresight devices that HLOS don't have permission to access. Such as
some TPDMs, they would be configured in NON-HLOS side, but it's necessary to
build Coresight path for it to debug. So there need driver to register dummy
devices as Coresight devices.
