Quick fix to borderline I2S timing issue
...
The initial receive on c_pdm_pcm channel ensures the mic array
decimator timing requirements are met when running configurations that
use the up and down-samplers.
However it appears to make the I2S timing very marginal, as subsequent
reads from the c_pdm_pcm channel will block for longer.
