Never mind, I handled the host->controller dir move myself, applied both to pci/aardvark for v4.19, thanks.

Great, thanks for doing this. I'm working on other Aardvark patches, so I'll make sure to rebase on top of the latest changes. Thanks, Thomas

In other to mimic other PCIe host controller drivers, introduce an advk_pcie_valid_device() helper, used in the configuration read/write functions.
