Subject: [PATCH] ASoC: qcom: q6asm: add support to wma config
Git-commit: 97163eadf18bff306b1cf8a8fa81938c5509899c
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518

Qualcomm DSPs expect wma v9 and wma v10 configs to be set for wma
decoders, so add the API to program the respective wma config to the DSP
