PCI: dwc: ep: Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit()

dw_pcie_ep_exit() API is undoing what the dw_pcie_ep_init() API has done
already (at least partly). But the API name dw_pcie_ep_exit() is not quite
reflecting that. So let's rename it to dw_pcie_ep_deinit() to make the
purpose of this API clear. This also aligns with the DWC host driver.
