sgtl5000 microphone gain only has 2 bits of resolution, so maximum value is 3.
From Eric Nelson: "We also found that for the microphones we have here (commodity PC boom mics) a default value of 2 for the gain gives the best results."
So change the default microphone gain as well.
The first bit is fine but the default change is not generally the sort of thing we do in ASoC - we generally go with the chip defaults, it saves on going round in circles arguing about what the defaults should be. Why would other systems not want a different default?
