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

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

[Pengpeng Hou]

The driver has an OF match table wired to .of_match_table, but does
not export the table with MODULE_DEVICE_TABLE().

Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias
information is generated for OF based module autoloading.

This is a source-level fix.  It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the platform driver, and the missing module alias publication.
