PCI: layerscape: Fix drvdata usage before assignment
Commit fefe6733e516 ("PCI: layerscape: Move struct pcie_port setup
to probe function") changed the init ordering of the pcie structure,
but started to use the pcie->drvdata field before initializing it.
Mayhem follows.
Fix this by moving the drvdata assignment right before the first use.
Tested on LS2085a.
