Subject: [PATCH 05/10] ASoC: fsl: fsl_qmc_audio: Introduce qmc_audio_pcm_{read,write}_submit()
Submitting data to QMC channels is done in several places: transfer
completions and DAI start. The operation done is simple and consist in
one function call.
With the future introduction of support for non-interleaved mode,
submitting data will be more complex.
To avoid copy/paste of code in several places, introduce
qmc_audio_pcm_{read,write}_submit() whose goal is to handle this
data submission.
