Roger also submitted a patch to do this. However, it is not
appropriate, so was dropped.
An HVMLite domain should assume there are no emulated devices. The very
old legacy devices will never be implemented, and any others we care
about possibly implementing in the future have APCI-based ways of
indicating support.
