ASoC: SOF: imx: add min/max channels for SAI/ESAI on i.MX8/i.MX8M

Browse Source 
This is identical with change for Intel platforms done with
commit 8c05246c0b ("ASoC: SOF: Intel: add min/max channels for SSP on Baytrail/Broadwell")
and fixes a regression on i.MX8/i.MX8M:

[   25.705750]  esai-Codec: ASoC: no backend playback stream
[   27.923378]  esai-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.

Fixes: 9b5db05936 ("ASoC: soc-pcm: dpcm: Only allow playback/capture if supported")
