Now we use the generic 'dmas' binding to passing such information.

If you look at linux-next tree these UART dma channels are already
been passed via the new 'dmas' method:

auart1: serial@8006c000 {
compatible = "fsl,imx28-auart", "fsl,imx23-auart";
reg = <0x8006c000 0x2000>;
interrupts = <113 72 73>;
dmas = <&dma_apbx 10>, <&dma_apbx 11>;
dma-names = "rx", "tx";
clocks = <&clks 45>;
status = "disabled";
};
