This patch moves AER error defines to drivers/pci/pci.h.
So that it unifies the error repoting codes at single place along with dpc

Hi Bjorn,

Based on your earlier comment I have moved AER and DPC error defined in driver/pci/pci.h
but I am not entirely comfortable with moving them there because

file such as
drivers/acpi/apei/ghes.c
include/ras/ras_event.h

they are outside of the scope of driver/pci/pci.h and they have to include the files
#include "../../pci/pci.h" and #include "../../../drivers/pci/pci.h" respectively.

hence my suggestion is to move error defines in include/linux/pci.h

let me know your view.

Regards,
Oza.
