That's the problem. MCP51 is the controller chip, not a codec chip. It's always supported by snd-hda-intel driver. CONFIG_SND_HDA_CODEC_* are configs to choose codec chips. Simply select all CONFIG_SND_HDA_CODEC_*=y if you are not sure (as they are default=y). I guess CONFIG_SND_HDA_CODEC_ANALOG=y should suffice but selecting others won't hurt except for a small memory footprint.
