  Report status code into DataHub.

                               classify the entity as well as an operation.
  @param  Instance             The enumeration of a hardware or software entity within
                               the system. Valid instance numbers start with 1.
  @param  CallerId             This optional parameter may be used to identify the caller.
                               This parameter allows the status code driver to apply different rules to
                               different callers.
  @param  Data                 This optional parameter may be used to pass additional data.

  @retval EFI_SUCCESS          The function completed successfully.
  @retval EFI_DEVICE_ERROR     Function is reentered.
  @retval EFI_DEVICE_ERROR     Function is called at runtime.
