Subject: [PATCH] efi: cper: Define macro for errors type

CPER defines errors type, which is currently in
form of raw numbers referenced from cper and
ghes_edac modules. CPER format sharable with
firmware. This errors type macro can be common
and share errors type between kernel and firmware
and eliminate magic numbers uses. Also will
simplify do code reuse in ghes_edac_report_mem_error.
