[PATCH 07/16] ASoC: SOF: Intel: hda-dai: use component_get_drvdata to find hdac_bus

[Pierre-Louis Bossart]

Remove the last usage of substream->runtime->private_data in the
HDAudio BE hw_params.

The SOF core saves the 'sdev' global context as component drvdata, and
we already save the bus information in sdev.
