Make 3.17-next boot on VBX3 with support of fsl-asoc-card
Support MicBias resistor and voltage in sgtl5000 for VBX3
audio: sgtl5000: Add MicBias resistor support in DT

Some systems may require a different resistor than the default one (4K).
This adds a property in sgtl5000 codec.
It keeps the default of 4K when nothing is specified so it does not break
existing code.

audio: sgtl5000: Add MicBias voltage support

Some systems may require to specify a bias different than default (1.25V).
This adds a property in sgtl5000 codec.
The property is specified in milli-volts so that it is coherent with datasheet.
