A common infrastructure for host devices is useful.  The Property
mechanism in hw/qdev-properties.c is especially good.  I think host
devices will also need to 2-step creation process (init and realize).

I think the qdev-properties.c code can mostly be shared.  It currently
uses the qdev DeviceState class but I think it only really access the
Property array.

Therefore it should be possible to really share a single copy of the
code.  We don't need to duplicate Property for host devices, instead
we can extract it out of hw/.
