ASoC: dapm: deprecate MICBIAS widget type
Commit 086d7f804e26 ("ASoC: Convert WM8962 MICBIAS to a supply widget",
2011-09-23) says:
A supply widget is generally clearer than a MICBIAS widget and a
mic bias is just a type of supply so use a supply widget for the
MICBIAS. This also avoids confusion with the routing when
connected to multiple inputs.
but this has never been documented as a policy. Add some comments to
make it clear.
