[PATCH v2 02/20] ASoC: omap-pcm: Support for binding the platform driver to dai devices

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

With the new calls it is going to be possible to bind the platform driver
to a dai device which makes it easier for us in a long run to handle DT
boots, and opens the possibility to move machine driver to generic simple
card.
