PCI: Make pci_bus_type constant
Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the pci_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
