coresight-replicator.o is built if CONFIG_CORESIGHT_LINKS_AND_SINKS is
defined. CORESIGHT_LINKS_AND_SINKS is a bool symbol. It depends on
CORESIGHT, which is also a bool symbol. CORESIGHT is a top level symbol,
available on arm and arm64.

I think coresight-replicator.o can only be built-in. So I suggest to use
builtin_platform_driver() instead.

Thanks,
