[PATCH 1/7] ASoC: SOF: Intel: hda-stream: export stream_get_position() helper

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

Export this helper so that we can report the DPIB position if the BPT
DMA do not complete - this is very useful to see if the DMA started or
gets stuck somehow with invalid bandwidth configurations.
