ASoC: fsl: Restore configuration of platform

This reverts commit 33683cbf49b54 ("ASoC: fsl: remove unnecessary
dai_link->platform").

dai_link->platform is needed. The platform component is
"snd_dmaengine_pcm", which is registered from cpu driver,

If dai_link->platform is not assigned, then platform
component will not be probed, then there will be issue:

aplay: main:831: audio open error: Invalid argument
