We print way too many messages like this:
pci 0000:00:00.0: no hotplug settings from platform
pci 0000:00:00.0: using default PCI settings
This usually happens when the platform doesn't supply an ACPI _HPP method,
but the method is optional, so there's no point in warning about it.
Not only are the messages useless, but we call pci_configure_slot() far too
many times, so they're repeated many times. I'll fix the overuse of
pci_configure_slot() too, but that will wait until the next merge window.
For now, just remove both log messages.
