Subject: [PATCH] ASoC: qcom: common: set correct directions for dailinks
Git-commit: a2120089251f1fe221305e88df99af16f940e236
Patch-mainline: v5.8-rc3
References: jsc#SLE-16518

Currently both FE and BE dai-links are configured bi-directional,
However the DSP BE dais are only single directional,
so set the directions as supported by the BE dais.

Fixes: c25e295cd77b (ASoC: qcom: Add support to parse common audio device nodes)
