[PATCH RESEND v6 03/18] EDAC/synopsys: Drop erroneous ADDRMAP4.addrmap_col_b10 parse

[Serge Semin]

Currently the ADDRMAP4.addrmap_col_b10 field gets to be parsed in case of
the LPDDR3 memory and Quarter DQ bus width mode. It's wrong since that
field is marked as unused for that mode in all the available DW uMCTL2
DDRC releases (up to IP-core v3.91a). Most likely the field parsing was
added by mistake as a result of the copy-paste from the Half DQ bus width
mode part of the same function. Even though the field is supposed to be
always set to the UNUSED value (0x1F) drop parsing it anyway so to
simplify the setup_column_address_map() method a tiny bit.
