ASoC: SOF: Intel: discard SoundWire configuration if HDaudio codec is reported

The machine driver and topology selection starts with I2S, then
SoundWire and last uses HDaudio as a fallback. That assumes that the
ACPI information is correct but there are of course exceptions to the
rule.

On a Lenovo platform, an external HDaudio codec is detected, but the
ACPI tables expose TWO RT711 jack codecs. This patch skips the
SoundWire selection in case an external HDaudio codec is detected -
which only works with the additional assumption that no one will mix
HDaudio and SoundWire.
