The driver in question is drivers/pci/controller/dwc/pci-layerscape.c I've also put the maintainers of this driver on CC. Looks like it uses a proper struct device. But it uses builtin_platform_driver_probe() and apparently it waits for the iommu which uses module_platform_driver(). Dunno if that will work together. The board device tree can be found here: arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts Attached is the log with enabled "probe deferral" messages enabled.
