ASoC: sun50i-codec-analog: Add support for internal bias
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.
