[PATCH 5.10 059/545] PCI: Add defines for normal and subtractive PCI bridges

[Greg Kroah-Hartman]

From: Pali Rohár <pali@xxxxxxxxxx>

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]
