ASoC: fsl_sai: add error message in case of missing imx-pcm-dma support

Browse Source 
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.
