ASoC: rt5651: Add support for jack detect using an external GPIO

Browse source

Some board designs hook the jack-detect up to an external GPIO,
rather then to one of the codec pins, add support for this.

Figuring out which GPIO to use is pretty much board specific so I've
chosen to let the machine driver pass the gpio_desc as data argument to
snd_soc_component_set_jack() rather then add support for getting the
GPIO to the codec driver. This keeps the codec code nice and clean.

Note that using an external GPIO for this conflicts with button-press
support, so this commit disables button-press support when an
external GPIO is used.
