2 nodes in an OpenFirmware device path are sufficient for the generic
check at the beginning of TranslateOfwNodes(). The driver specific
branches check for the necessary nodes individually.
The number of nodes saved for examination is unchanged.

Set the boot order based on configuration retrieved from QEMU.
Attempt to retrieve the "bootorder" fw_cfg file from QEMU. Translate the
OpenFirmware device paths therein to UEFI device path fragments. Match the
translated fragments against the enumerated BootOptionList, and rewrite
the BootOrder NvVar so that it corresponds to the order described in
fw_cfg.
The user is expected to configure working boot options first.
Tested via virt-manager's boot order widget.
