If the imx-pcm-dma is required we need to have the module enabled. For all NXP/FSL sound cards using the ASoC architecture this is the case but in case of using the simple-audio-card sound card this isn't the case. In such case the driver probe fails silently and the card isn't available. It took a while to find the missing Kconfig. Make this easier for others by printing a error if this the module isn't available but required by the HW.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
