[PATCH v2] coresight: dummy: add missing MODULE_DEVICE_TABLE()

[PATCH v2] coresight: dummy: add missing MODULE_DEVICE_TABLE()

[Pengpeng Hou]

The CoreSight dummy driver has an OF match table wired into its platform
driver, but does not export the table to module metadata. A modular build
therefore lacks OF aliases for automatic loading.

Export dummy_match with MODULE_DEVICE_TABLE().
