[PATCH v5 02/10] ASoC: imx-pcm-dma: DT support

[mpa@pengutronix.de (Markus Pargmann)]

This patch adds the possibility to pass a of_node as platform_data which
is used by generic-pcm-dma to request a DMA slave channel.

Signed-off-by: Markus Pargmann <mpa@pengutronix.de>

Notes:
    Changes in v5:
     - Use dev.parent pointer to get the of_node.
