When initially added, a mistake was made in the definition of the codec. Despite the fact that the DMIC line is connected on the side of the codec chip, and relevant passive components, including 0-ohm resistors connecting the dmics, are present, the dmic line is still cut in another place on the board, which was overlooked. Correct this by replacing the dmic configuration with a comment describing this hardware detail. While at it, also add missing regulators definitions. This is not a functional change as all the relevant regulators were already added via the other rail supplies.
