Subject: [PATCH 09/20] EDAC/synopsys: Drop struct ecc_error_info.blknr field

Even though the ECC(C|U)ADDR1 CSR description indeed says it's a "Block
number" in the DW uMCTL2 DDRC hw reference manuals, the corresponding
register field name (ECC(C|U)ADDR1.ecc_(un)corr_col) and the rest of the
hw documentation refer to the field as the SDRAM address column. Thus
let's use the already available ecc_error_info.col field to read the
column number to and drop the questionable ecc_error_info.blknr field for
good.
