ASoC: Intel: HDA: two cleanups

Browse source 
Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

One removal of a non-existent Kconfig initialization and one
correction to enable SoundWire link when no HDaudio external codec is
detected. This will generate more information and help resolve cases
where the ACPI information is incorrect.
