ASoC: qcom: qdsp6: Set channel mapping instead of fixed defaults
When constructing packets to DSP, the Audioreach code uses 'struct
audioreach_module_config' to configure parameters like number of
channels, bitrate, sample rate etc, but uses defaults for the channel
mapping.
Rework this code to copy the channel mapping from 'struct
audioreach_module_config', instead of using the default. This requires
all callers to fill that structure: add missing initialization of
channel mapping.
Entire patch makes code more logical and easier to follow:
1. q6apm-dai and q6apm-lpass-dais code which allocates 'struct
audioreach_module_config' initializes it fully, so fills both
the number of channels and the channel mapping.
2. Audioreach code, which uses 'struct audioreach_module_config' when
constructing packets, copies entire contents of passed config, not
only pieces of it.
