In order to properly bias headset microphones, there should be a pull-up resistor between pins HBIAS and MIC2P. This can be an external resistor, but the codec also provides an internal 2.2K resistor which is enabled by a register. This patch enables or disables the internal bias resistor based on a device tree property.
