[PATCH RESEND v3 04/17] EDAC/synopsys: Drop erroneous ADDRMAP4.addrmap_col_b10 parse

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 has
been added by mistake as a result of the copy-paste from the Half DW bus
width mode part of the same function. Drop it from the driver for good
then.
