Sure.

This line goes away.

This line is changed to

obj-$(CONFIG_NETFILTER_XT_DSCP) += xt_dscp.o

Kconfig file NETFILTER_XT_TARGET/MATCH_DSCP are changed to
select new NETFILTER_XT_MATCH_DSCP.

This has been done before, see e.g.
28b949885f80 ("netfilter: xtables: merge xt_MARK into xt_mark")

you can follow this almost 1:1.
