By passing no flags when calling snd_dmaengine_pcm_register() from tegra_pcm.c, we end up using dma_request_slave_channel() rather than dmaengine_pcm_compat_request_channel(), and hence rely on the standard DMA DT bindings and stashing the DMA slave ID away during channel allocation. This means there's no need to use a custom DT property to store the slave ID. So, remove all the code that parsed it.
