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().
Fixes: 9d3ba0b6c056 ("Coresight: Add coresight dummy driver")

Changes since v1: https://lore.kernel.org/all/20260704121621.48544-1-pengpeng@iscas.ac.cn/
- add the requested Fixes tag
- carry Jie Gan's conditional Reviewed-by after making that change
- rebase onto v7.2-rc4
