Just reuse dibbi_conns, just as is done with fizz_conns.

Actually, what would be better is to rename these _conns arrays to something
like:

static const char *const port_db_conns[] = { "Port D", "Port B", NULL };

That's much cleaner IMHO.

Can you post a small patch series? The first renames these conns arrays,
the second adds Taranza support.

Thank you!
