If a pci-2-pci bridge supports hot-plug functionality but there are no devices connected to it, reserve IO/mem in order to be able to attach devices later. Do not waste space, use minimum allowed.

Should we also check for hotplug-capable pci express ports while being at it?
Can be a separate patch?
I think it can be. This one handles pci-2-pci bridges and avoids PCIe by choice. I do plan to handle PCIe hotplug corners later.
