commit 904b10fb189cc15376e9bfce1ef0282e68b0b004 upstream.
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]
