The default quirk for a CHT es8316 codec using device is:

        } else {
                /* Others default to internal-mic-in1-map, mono-speaker */
                quirk = BYT_CHT_ES8316_INTMIC_IN1_MAP |
                        BYT_CHT_ES8316_MONO_SPEAKER;
        }

So this just drops the BYT_CHT_ES8316_MONO_SPEAKER from the default quirks.

Yes defaulting to mono is a bit weird, but the es8316 is mostly
used in very low budget devices which often have only 1 speaker.

Regards,

Hans
