I took more time to look at this, to summarize my remarks on the other
patches

I think we don't need properties. The info in the msi_desc can come
from the pci_dev which we have easy access to. This seems overall
clearer

The notable one is the sysfs, but that is probably better handled by
storing a

  const char *sysfs_label

in the dev->msi and emitting that instead of computing it.
