usage of hdac-hdmi is removed in newer mach drivers (like 
sof_da7219_max98373, sof-pcm512 and ehl_rt5660 -> and there's no select 
for SND_SOC_HDAC_HDMI for these). For older ones, we've kept hdac-hdmi in 
to keep compatibility.

For sof_sdw, there are still calls to hdac_hdmi_jack_init() and friends
in sof_sdw_hdmi.c, so this is a real problem.

I'd say a better fix is that we remove the hdac-hdmi support from sof_sdw.
I can do a patch for that.

I checked all the related mach drivers and the Kconfig definitions are 
correct for others. So select is done to HDAC_HDMI whenever the mach 
driver uses hdac_hdmi_jack_*().
