Sebastian Ott aa3b7c2967 s390/pci: prevent inadvertently triggered bus scans
Initialization and scanning of the pci bus is omitted on older
machines without pci support or if pci=off was specified. Remember
the fact that we ran without pci support and prevent further bus
scans during resume from hibernate or after receiving hotplug
notifications.
