ASoC: SOF: Intel: fix SoundWire/HDaudio mutual exclusion

Browse Source 
The functionality described in Commit 61bef9e68d ("ASoC: SOF: Intel: hda: enforce exclusion between HDaudio and SoundWire")
does not seem to be properly implemented with two issues that need to
be corrected.

a) The test used is incorrect when DisplayAudio codecs are not supported.

b) Conversely when only Display Audio codecs can be found, we do want
to start the SoundWire links, if any. That will help add the relevant
topologies and machine descriptors, and identify cases where the
SoundWire information in ACPI needs to be modified with a quirk.
