ASoC: rk3399_gru_sound: Add DAPM pins, kcontrols for jack detection
PulseAudio (and perhaps other userspace utilities) can not detect any jack for rk3399_gru_sound as the driver doesn't expose related Jack kcontrols. This patch adds two DAPM pins to the headset jack, where the snd_soc_card_jack_new() call automatically creates "Headphones Jack" and "Headset Mic Jack" kcontrols from them. With an appropriate ALSA UCM config specifying JackControl fields for the "Headphones" and "Headset" (mic) devices, PulseAudio can detect plug/unplug events for both of them after this patch.
