  Even though the ECC(C|U)ADDR1 CSR description indeed says it's a "Block
number" in the DW uMCTL2 DDRC IP-core databooks, the corresponding
register field is named as ECC(C|U)ADDR1.ecc_(un)corr_col (which means ECC
(un)corrected column) and in the rest of the document it's referred as the
SDRAM address column. Thus 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.
