ASoC: intel: skl_hda_dsp_common: create HDMI jack kctl 



This patch call snd_jack_add_new_kctl() to create the HDMI jack kctls.
Userspace needs these kctls to detect the hdmi monitor hotplug.

In /usr/share/alsa/ucm, the config file needs to assign a jack kctl to
"JackControl" to let PA get the jack hotplug status.
