MLK-12057 ASoC: imx-wm8960: add headphone/micphone/headset jack support

Add headphone/micphone/headset jack support for different board.

There are headphone detect gpio and microphone detect gpio which
can be configured from device tree.
If headphone and microphone using the same gpio for jack detect,
it suppose to be a headset and will register a headphone jack for it.
If headphone and microphone using different gpio for jack detect,
it suppose not to be a headset, and will register headphone jack
and microphone jack respectively.

Is't not appropriate to set the adc data output in machine driver.
It will not be compatibly when we change hardware connection.
wm8960 codec driver has added "ADC Data Output Select" kcontrol,
so that we can set the ADC data output from user space.
