ASoC: SOF: Intel: hda: retrieve DMIC number for I2S boards 

We currently extract the DMIC number only for HDaudio or SoundWire
platforms. For I2S/TDM platforms, this wasn't necessary until now, but
with devices with ES8336 we need to find a solution to detect dmics
more reliably than with a DMI quirk.
