ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of()
Currently when of_node of the "PCM" device is null
dmaengine_pcm_request_chan_of() function will bail out, including cases
when custom DMA device is intended to be used. To have the channels
properly requested when custom DMA device is provided extend the of_node
test to also consider dma_dev->of_node.
