ASoC: Add SND_SOC_DAPM_PIN_SWITCH controls for exposing DAPM pins
On some systems it is desirable for control for DAPM pins to be provided to user space. This is the case with things like GSM modems which are controlled primarily from user space, for example. Provide a helper which exposes the state of a DAPM pin to user space for use in cases like this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
