amd64_edac: Cleanup NBSH cruft
Remove reporting of errors with UC bit set - this is done by the MCE decoding code anyway and this driver deals with DRAM ECC errors only. UC (NB uncorrectable error) doesn't necessarily mean it is a DRAM error. Remove unused macros while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
