ARM: dts: OMAP3-N900: Add microphone bias voltages
commit 1819e3034ee26ffadc71880064ed8b8e7d74f52c upstream.
N900 audio recording needs that codec provides bias voltage for integrated
digital microphone and headset microphone depending which one is used.
Digital microphone uses 2 V bias and it comes from the codec A part. Codec
B part drives the headset microphone bias and that is set to 2.5 V.
