I don't remember but some sof might use without platform it I thought.
But, current ALSA SoC can handle NULL platform today.
Maybe/Maybe not support timing issue ?

I think this is same as
3e6de89409bf7ad149bfb05dd0dce6c5678ea0a8
("ASoC: soc-topology: fix modern dai link style")
Above one is also OK, but now we can use NULL platform.
I'm not familiar with SOF, but maybe like this code instead
of having dummy platform can salve your issue ?
if (link->platforms) {
link->platforms->name = dev_name(sdev->dev);
}
