The link could come up at a later point in time. Please refer to the
implementation of:
dw_pcie_host_init() in drivers/pci/controller/dwc/pcie-designware-host.c
wherein we have the following:
	/* Ignore errors, the link may come up later */
	dw_pcie_wait_for_link(pci);

It seems to me that the logic behind ignoring the absence of the link
within cdns_pcie_host_link_setup() instead of erroring out, is similar to
that of dw_pcie_wait_for_link().
