ASoC: Intel: sof_sdw: allow HDaudio/HDMI disable

For tests, it's rather common to disable the HDaudio links and codecs
in the build. Since we already get a codec_mask parameter indicating
that there are no codecs detected, it's straightforward to skip the
HDMI dailink creation and create a card.

Note that when disabling HDMI, a modified topology without HDMI
pipelines needs to be provided as well.
