ASoC: Intel: sof_sdw: Always register the HDMI dai links

The topology files for SDW devices require HDMI dai links to be present and
this is granted under normal conditions but in case of special use cases
the display (i915) driver might not be enabled due to deny-listing,
booting with nomodeset or just not compiled at all.

This should not block the non HDMI audio to be usable so register the dai
links unconditionally. The code has been prepared for this and in case of
no HDMI audio the link is created with dummy codec.
