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.
