ASoC: Intel: skl_hda_dsp_generic: Implement add_dai_link to filter HDMI PCMs

If the system does not have iDisp codec then mark the HDMI PCM link as
ignore.
This ensures that HDMI PCMs will not be created when there is no iDisp
codec available.

When iDisp codec is not present and the HDMI PCMs were created they were
not operational, all operations would fail on them.

With this patch it is possible to load the topology with HDMI links, but
gives the ability to ignore them and thus prevent the creation of the
nonworking PCM devices.
