ASoC: Hook up microphone jack detection on 1133-EV1 board
Note that since all the microphones share a bias there is a single jack exported for all three, even though there are two physical connectors plus the soldered down silicon mic. Note also that the SiMic is always present by default. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
