ASoC: wm8994: Keep AIF3 tristated when not in use
Since AIF3 shares clock signals with other audio interfaces in order to ensure it doesn't drive undesirable clocks we need to tristate it. Rather than forcing the machine driver to do so have the driver do this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
