PCI: Remove unused PCI_SUBTRACTIVE_DECODE
2fe2abf896c1 ("PCI: augment bus resource table with a list") added
PCI_SUBTRACTIVE_DECODE which is put into the struct pci_bus_resource flags
field but is never read. There seems to never have been users for it.
Remove both PCI_SUBTRACTIVE_DECODE and the flags field from the struct
pci_bus_resource.
