/**
  The HII driver handle passed in for HiiDatabase.NewPackageList() requires
  that there should be DevicePath Protocol installed on it.
  This routine create a virtual Driver Handle by installing a vendor device
  path on it, so as to use it to invoke HiiDatabase.NewPackageList().
  The Device Path created is a Vendor Device Path specific to Intel's implemenation
  and it is defined as HII_VENDOR_DEVICE_PATH_NODE.
  

  @param  DriverHandle           Handle to be returned

  @retval EFI_SUCCESS            Handle destroy success.
  @retval EFI_OUT_OF_RESOURCES   Not enough memory.
