PCI: Add defines for normal and subtractive PCI bridges
Add these PCI class codes to pci_ids.h:
PCI_CLASS_BRIDGE_PCI_NORMAL
PCI_CLASS_BRIDGE_PCI_SUBTRACTIVE
Use these defines in all kernel code for describing PCI class codes for
normal and subtractive PCI bridges.
[bhelgaas: similar change in pci-mvebu.c]
