OK, this can be dropped. Would you consider doing something like the
patch below?
The only reference I can find to MICBIAS being legacy is in commit
086d7f804e26 ("ASoC: Convert WM8962 MICBIAS to a supply widget",
2011-09-23) and some following commits, there don't seem to be any
comments in the documentation indicating that it's not to be used.
