I'm not sure we have any prior art in this respect. I feel it is a bit
odd-ball that AC97 and ES1370 are uppercase in qdev, so in that respect
the ac97/es1370 aliases are nice.

Libvirt uses uppercase form, so wouldn't be impacted if we removed the
aliases.

I don't have a strong preference either way.

I'd suggest splitting the removal of the aliases into a separate patch
since it isn't strictly neeeding to be done at the same time.

If you split off, then I'm happy for both bits to be
