ASoC: sgtl5000: Fix maximum value for microphone gain
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.
