This entry is for selecting "PCM" (DMA) component for the link. 
For proper matching we need to use names of devices for which
the dmaengine based PCM component is registered (with a call to
samsung_asoc_dma_platform_register()).

We can't use platform_of_node because 2 PCM components ("3830000.i2s", 
"samsung-i2s-sec") are now associated with same DT node.
