"Mic Bias" is DAPM_SUPPLY so it has to be connected in the route accordingly. Fixes audio capture on the board.

Here's additional data. Without this patch there are these errors below when registering the card:

This don't happen on v3.18 so in that sense Peter's patch is kind of half-regression fix for v3.19. On the another hand DMIC recording is not working anyway since codec mic bias definition is missing at the moment from omap3-n900.dts.
