So AFAICT, CONFIG_PCI_HOTPLUG_OLD is still defined for x86 targets:

$ git grep PCI_HOTPLUG_OLD
default-configs/i386-softmmu.mak:CONFIG_PCI_HOTPLUG_OLD=y
default-configs/x86_64-softmmu.mak:CONFIG_PCI_HOTPLUG_OLD=y
...

I believe the reasoning was that for other targets, pci_add/del were
never properly supported and we should go directly to device_add/del
instead.
