I don't think these are sensible reasons to block progress on qdev
conversions.

The machine config file does not exist, and won't be useful until the
devices are converted to qdev.

-pcidevice can be useful now, for devices converted to qdev, but it
doesn't fully work for certain incomplete conversions.  While that's
inacceptable for a release, is it really so horrible as a transient step
now?  Besides, we can easily flag incompletely converted devices, and
make -pcidevice not touch them.
