Subject: [RESEND 1/5] RAS, trace: Update error definition format

Previous format definition uses MACRO BIT(...), which is not very
maintainable as Bjorn mentioned before:
"I'd like to see all those "BIT(...)" things changed to use the #defines
that already exist in include/uapi/linux/pci_regs.h, e.g.,
PCI_ERR_COR_RCVR.  That way grep will find these uses, which will make
maintenance easier."

Now here it is.
