ASoC: SOF: Intel: add min/max channels for SSP on Baytrail/Broadwell
Major regressions were detected by SOF CI on CherryTrail and Broadwell:
[ 25.705750] SSP2-Codec: ASoC: no backend playback stream
[ 27.923378] SSP2-Codec: ASoC: no users playback at close - state
This is root-caused to the introduction of the DAI capability checks
with snd_soc_dai_stream_valid(). Its use in soc-pcm.c makes it a
requirement for all DAIs to report at least a non-zero min_channels
field.
For some reason the SSP structures used for SKL+ did provide this
information but legacy platforms didn't.
