PCI: artpec6: Implement dw_pcie_ep operation get_features
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.
