Don't think this something we should care about.
This is a test driver, and if someone plugs in a PCIe endpoint on the PCIe bus
that runs the PCIe endpoint framework, and the pci-epf-test driver, they
obviously know what they are doing, and want good/important warnings.

Will user proper API in V2.
