Subject: [PATCH 2/3] EDAC: synopsys: Reorganizing the output message for CE/UE

The origin way which call sprintf() function two or three times to
output message for CE/UE is incorrect, because it won't output all the
message needed, instead it will only output the last message in
sprintf(). So the simplest and most effective way to fix this problem
is reorganizing all the output message needed for CE/UE into one
sprintf() function.
