This log message should be a debug message, because it
doesn't return directly but continue next loop.

This driver is used to accept the message from rpmsg audio
channel, and if this driver is probed, it will help to register
the platform driver, the platform driver will use this
audio channel to send and receive message to and from Cortex-M
core.

The platform device is not registered by device tree or
cpu dai driver, it is registered by the rpmsg channel,
So add a dedicated machine driver to handle this case.

Add snd_soc_pcm_component_ack back, which can be used to get updated
buffer pointer in platform driver.
On Asymmetric multiprocessor, this pointer can be sent to Cortex-M
core for audio processing.

fsl_rpmsg cpu dai driver is driver for rpmsg audio, which is mainly used
for getting the user's configuration from device tree and configure the
clocks which is used by Cortex-M core. So in this document define the
