PCI: imx6: Start link in Gen1 before negotiating for Gen2 mode

This patch first forces the link into Gen1 mode before starting up the link
and, only after the link is up, start negotiating possible Gen2 mode
operation.  This is because without such sequence, some PCIe switches are
not detected at all.
