ASoC: sgtl5000: Fix maximum value for microphone gainT30_LinuxImageV2.0Alpha1_20130122
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.
