PCI: dwc: Add ->get_features() callback function to dw_pcie_ep_ops 



Each platform using Designware PCIe core can support different set of
endpoint features. Add a new callback function ->get_features() in
dw_pcie_ep_ops so that each platform using Designware PCIe core can
advertise its supported features to the endpoint function driver.
