audioreach: lemans-evk: Enable stereo capture on MultiMedia2 frontend

Browse source 
The LEMANS-EVK capture frontend for MultiMedia2 currently constrains
channels to mono (min=1, max=1). This prevents opening the PCM with
2-channel (stereo) configurations and typically leads to:
  arecord: audio open error: Invalid argument

Update the STREAM_SG_PCM_ADD() parameters to allow up to 2 channels
(min=1, max=2) for S16_LE at 48 kHz. This aligns the front-end PCM
capability with common SoC/codec routes that can support stereo capture,
while preserving backward compatibility with mono.
