These codecs require individual configurations and those "../codecs/rt5631.h" and "../codecs/rt5677.h" aren't compatible at a quick glance. The tegra_rt5677 also uses outdated GPIO API and etc. Hence the new driver should be a better base anyways. Overall it shouldn't worth time and effort trying to squeeze these drivers into a single one, IMO.
