ASoC: q6dsp6: q6afe-dai: add missing channels to MI2S DAIs 
For some reason, the MI2S DAIs do not have channels_min/max defined.
This means that snd_soc_dai_stream_valid() returns false,
i.e. the DAIs have neither valid playback nor capture stream.

It's quite surprising that this ever worked correctly,
but in 5.7-rc1 this is now failing badly: :)

Commit 0e9cf4c452 ("ASoC: pcm: check if cpu-dai supports a given stream")
introduced a check for snd_soc_dai_stream_valid() before calling
hw_params(), which means that the q6i2s_hw_params() function
was never called, eventually resulting in:

    qcom-q6afe aprsvc:q6afe:4:4: no line is assigned

... even though "qcom,sd-lines" is set in the device tree.

Commit 9b5db05936 ("ASoC: soc-pcm: dpcm: Only allow playback/capture if supported")
now even avoids creating PCM devices if the stream is not supported,
which means that it is failing even earlier with e.g.:

    Primary MI2S: ASoC: no backend playback stream

Avoid all that trouble by adding channels_min/max for the MI2S DAIs.
