dma: imx-sdma: move to generic device tree bindings
Update imx-sdma driver to adopt generic DMA device tree bindings. It calls of_dma_controller_register() with imx-sdma specific of_dma_xlate to get the generic DMA device tree helper support. The #dma-cells for imx-sdma must be 3, which includes request ID, peripheral type and priority. The existing way of requesting channel, clients directly call dma_request_channel(), still work there, and will be removed after all imx-sdma clients get converted to generic DMA device tree helper.
