[alsa-devel] [PATCH 08/19] ASoC: Intel: boards: add DEEP_BUFFER support for BYT/CHT/BSW

[Pierre-Louis Bossart]

Add dai links to enable additional playback stream with deeper
buffer for lower power consumption.
The normal and DEEP_buffer streams are not mutually exclusive,
content will be mixed by the DSP.
