Add 'struct coresight_path' to store the data that is needed by coresight_enable_path/coresight_disable_path. The structure will be transmitted to the helper and sink device to enable related funcationalities.

I don't think renaming 'path' to 'cs_path' is worth the churn. It's in a lot of places in this change, but I think path is already good enough.

return;

coresight_get_sink() is always called with cs_path->path, so we might as well make it take a whole path struct. The same with any of the other functions that operate on path like coresight_get_source().
