[ Upstream commit ba4e5abc6c4e173af7c941c03c067263b686665d ]
With additional checks on dailinks, we see errors such as
[ 3.000418] sof-nocodec sof-nocodec: CPU DAI DMIC01 Pin for rtd
NoCodec-6 does not support playback
It's not clear why we set the dpcm_playback and dpcm_capture flags
unconditionally, add a check on number of channels for each direction
to avoid invalid configurations.
Fixes: 8017b8fd37bf5e ('ASoC: SOF: Add Nocodec machine driver support')
