I thought about this, but if I keep it in drivers/pci.h,
then AER's defines have to be in that as well. (for unification)

and then all the dependent files who are using AER_FATAL such as 
drivers/acpi/apei/ghees.c
have to go on including this drivers file which is odd way of doing it.

So I am not very sure about this....since AER_FATAL are in aer.h, I have 
made dpc.h
