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 current list of boot options, and rewrite
the BootOrder NvVar so that it corresponds to the order described in fw_cfg.
Platform BDS should call this function after EfiBootManagerConnectAll () and
EfiBootManagerRefreshAllBootOption () return.
@retval RETURN_SUCCESS BootOrder NvVar rewritten.
@retval RETURN_UNSUPPORTED QEMU's fw_cfg is not supported.
@retval RETURN_NOT_FOUND Empty or nonexistent "bootorder" fw_cfg
file, or no match found between the
"bootorder" fw_cfg file and BootOptionList.
@retval RETURN_INVALID_PARAMETER Parse error in the "bootorder" fw_cfg file.
@retval RETURN_OUT_OF_RESOURCES Memory allocation failed.
@return Values returned by gBS->LocateProtocol ()
