[PATCH v4 1/6] PCI: layerscape: remove ls_pcie_establish_link()

[Minghuan Lian]

ls_pcie_establish_link() does not do any real operation, except
to wait for the linkup establishment. In fact, this is not
necessary. Moreover, each PCIe controller not inserted device
will increase the Linux startup time about 200ms.
