PCI: dwc: Detect iATU settings after getting "addr_space" resource

Previously, dw_pcie_ep_init() did:

  dw_pcie_iatu_detect(pci);
  res = platform_get_resource_byname(pdev, IORESOURCE_MEM, "addr_space");
  if (!res)
    return -EINVAL;

The platform_get_resource_byname() can fail, and dw_pcie_iatu_detect()
doesn't depend on the "addr_space" resource, so delay it until afterwards,
i.e.,

  platform_get_resource_byname(pdev, IORESOURCE_MEM, "addr_space");
  dw_pcie_iatu_detect(pci);
