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 as well.

Changes from v1:
*) Re-based and Re-worked to latest kernel 5.10.0-rc2+ (now has generic
   binding for EP)

Patch series is created on top of NTB series [2]

v1 of the patch series can be found @ [1]
