Patch series
*) Adds support to add virtual functions to enable endpoint controller
   which supports SR-IOV capability
*) Add support in Cadence endpoint driver to configure virtual functions
*) Enable pci_endpoint_test driver to create pci_device for virtual
   functions

Here both physical functions and virtual functions use the same
pci_endpoint_test driver and existing pcitest utility can be used
to test virtual functions also.
