Just wondering, I note in really_probe() we configure the pin controller,
active the pm_domain etc before probing a driver.

Would it make sense for the issue you mention above to similarly
amend pci_scan_device() to enable whatever clocks or regulators
are described in the devicetree as providers for the given PCI device?

Thanks,

Lukas
