The next coming i.MX6 Solo X SoC also contains SAI module while we use
imp_pcm_init() for i.MX platform.
So this patch adds one compatible route for imx6sx and updates the DT
doc accordingly.

I've applied this, though obviously it'd be better if we had dmaengine
support for this SoC so that it was just a compatible string update and
didn't require any code.

Hmm...actually imx_pcm_init() is just a shell calling dmaengine while it
has its own config and flags. So we still need to extinguish these two
elements for them even if using devm_snd_dmaengine_pcm_register() eventually.
But the idea to merge them into one entry should be great for 3rd platform
or even further one. And a patch for imx-pcm-dma and all callers of it
would be needed then.
Thank you,
