Subject: [PATCH v4 11/18] EDAC/synopsys: Pass syndrome to EDAC error handler

EDAC MC error handler permits specifying a corrected error syndrome which
then will be printed as a part of the generic error message. Since it's
available in the error info structure pass it to the
edac_mc_handle_error() function.

Changelog v4:
- Get syndrome from the ECCSTAT.ecc_corrected_bit_num field rather than
  from ECCCSYN2. The later CSR in fact contains ECC.
