OK, so the fix for 4.13 would be either to cherry-pick this commit, or
just to re-add "RT5677CE:00" to i2c_id temporarily as a quick band-aid
fix (and remove again in 4.14).

The former is cleaner, but it's bigger, while the latter is a safer
oneliner at the late RC stage.

I leave the decision to Mark.
