ASoC: Intel: sof_rt5682: fix out-of-bounds array access
Starting from ADL platform we have four HDMI PCM devices which exceeds
the size of sof_hdmi array. Since each sof_hdmi_pcm structure
represents one HDMI PCM device, we remove the sof_hdmi array and add a
new member hdmi_jack to the sof_hdmi_pcm structure to fix the
out-of-bounds problem.
