Alternatively we can add new structures with new
structure IDs, pointed to from PCI configuration space.

As we don't yet have devices or drivers with 64 bit features,
I decided we don't need high feature bits in legacy space.
This also frees up feature bit 31 as we don't need it
to enable high feature bits anymore.

KVM tool actually has support for 64bit features, we can probably remove
that when Pekka isn't looking :)

What about the Windows drivers?

Probably some small adjustments will be required,
but I don't see any major problem here.
