Now that we associate a device_t with ACPI device handles, lookup the

device associated with any PCI devices that are enumerated in the ACPI
tree when adding children to an ACPI PCI bus and remove the duplicate
ACPI-only device_t and replace the device_t associated with the handle with
the ACPI and PCI aware device_t.
