U-Boot error because of wrong USB endpoint

[dolcini]

With U-Boot 2025.04, i.MX8M Plus SoC, and latest UUU release, there are errors during download using fastboot protocol.

The download succeed despite these errors.

The issue seems related to some hard-coded USB endpoints in the UUU tool.

It should be other issue
