commit abe3b6727b653307c27870a2d4ecbf9de4e914a5
Author: Olivier Moysan <olivier.moysan@st.com>

ASoC: cs42l51: add dac mux widget in codec routes

Add "DAC mux" DAPM widget in CS42l51 audio codec routes,
to support DAC mux control and to remove error trace
"DAC Mux has no paths" at widget creation.
Note: ADC path of DAC mux is not routed in this patch.
