You're right, it's ugly to use this sort of path to a private PCI
header file from outside drivers/pci.

Could you just add DPC_FATAL to include/linux/aer.h? Maybe we
discarded that for some reason? Having pcie-dpc.c include linux/aer.h
seems like it would be better than having this ACPI code include
"../../pci/pci.h"
