PCI: endpoint: Create configfs entry for EPC device and EPF driver
Invoke APIs provided by pci-ep-cfs to create configfs entry for every EPC device and EPF driver to help users in creating EPF device and binding the EPF device to the EPC device. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
