ASoC: qcom: x1e80100: Correct channel mapping

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:

X1E80100 CRD is the first board, which comes with four speakers, so we
still keep fixing and adding missing pieces.

The board has speaker arranged as left front+back and then right
front+back.  Using default channel mapping causes front right speaker to
play left back stream.

Adjust the channel maps for frontend DAIs to fix stereo and four-channel
playback.
