All non-DWC EPC drivers implement (struct pci_epc *)->ops->get_features(). All DWC EPC drivers implement (struct dw_pcie_ep *)->ops->get_features(), except for pcie-artpec6.c. epc_features has been required in pci-epf-test.c since commit 6613bc2301ba ("PCI: endpoint: Fix NULL pointer dereference for ->get_features()"). A follow-up commit will make further use of epc_features in EPC core code. Implement epc_features in the only EPC driver where it is currently not implemented.
