ASoC: msm8916-wcd-analog: Add MIC BIAS Internal3
PM8916 has three TX inputs that each have an (optional) internal
RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported.
TX3 does not have its own MIC BIAS supply, instead it is also supplied
from MIC_BIAS1.
Now that we have simplified the MIC BIAS Internal* implementation
we can easily add support for it:
Add a MIC BIAS Internal3 supply that enables the internal RBIAS
resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.
