[PATCH 4/6] PCI: imx6: Probe the PCIe in fs_initcall()

[Marek Vasut <marex@denx.de>]

Probe the PCIe driver in fs_initcall() instead of module_init()
to assure that pci_assign_unassigned_resources(); will be called
early. This function is called in dw_pcie_host_init(), which is
in turn called from imx6_add_pcie_port(), which is called from
imx6_pcie_probe() . If this is not called early, we will hit
resource collisions since pcieport driver is then probed way too
late.
