Faster USB chipset is more expensive and potentially also physically larger with more traces on the circuit board to deal with I imagine. And faster data speeds require more attention to how the traces are routed to prevent interference. I very much doubt this is anything other than to save a relatively small amount on materials and engineering costs, on an already overpriced phone, and/or to try and “encourage” you to use iCloud by making offline sync and backup painfully slow.
