[U-Boot] [RFC] Duplicated string prefix

You should be able to tell beforehand how much this could save by
analyzing the strings in a current U-Boot compile, right?  This way one
would know whether it makes sense to embark on that journey.

_If_ we decide to go down that route, I'd suggest using functions
comparable to what Linux offers, e.g. something like pr_err, pr_warning,
etc.

Cheers
