ASoC: Intel: don't check number of sdw links when set

Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:

Currently, we assume that the PCH DMIC pins are pin-muxed with SoundWire
links. However, we do see a HW design that use PCH DMIC along with 3
SoundWire links. Remove the check and add warning to let users know that
SoundWire MIC and PCH DMIC are both present and they could overwrite it
with kernel params.
