Since no PCIe controller drivers call this, this change is not required for now. But, Renesas R-Car Gen4 PCIe controller driver will call this and if the controller driver is built as a kernel module, the following build error happens. So, expose dw_pcie_ep_exit() for it. ERROR: modpost: "dw_pcie_ep_exit" [drivers/pci/controller/dwc/pcie-rcar-gen4-ep-drv.ko] undefined!
