Hmm, makes sense to me. Maybe we should really hide those behind a
debug switch, the question is whether asking the user to boot with
"efi_debug=on" in order to see the regions is ok. And I think it is ok
because we do that when debugging other stuff so I don't see anything
different here.

And then when they're disabled by default, we don't really need to
shorten them as they're pure debug output then.

Matt?
