ASoC: qcom: x1e80100: Support boards with two speakers

Some Qualcomm X1E laptops have only two speakers.  Regardless whether
this sound card driver is suitable for them (we could re-use one for
some older SoC), we should set reasonable channel map depending on the
number of channels, not always 4-speaker setup.

This change is necessary for bringing audio support on Lenovo Thinkpad
T14s with Qualcomm X1E78100 and only two speakers.
