Daniel Drake dbaccc0cca ALSA: hda - Tweak OLPC XO-1.5 microphone bias ...

Our contacts at Conexant suggested that we reduce the external
microphone bias to 50% in order to center the input signal with
the DC input range of the codec. This is because the microphone
port is DC coupled for potential use with sensors.
