Summary

Changing the pci ids is valuable in some situations. The Intel GOP
driver requires that some pci ids of the lpc bridge are aligned with the
physical values of the host lpc bridge. Another use case are oracles
virtio driver. They require different subvendor id than the default one.
For that reason, create a helper which makes it easy to read pci ids
from bhyve config. Additionally, this helper ensures that all emulation
devices are using the same config keys.
