ARM: dts: add generic DMA device tree binding for mxs-dma
Add generic DMA device tree binding for mxs-dma. The changes include:
* Add channel interrupts into DMA controller nodes
* Add properties '#dma-cells' and 'dma-channels' for DMA controller nodes
* And properties 'dmas' and 'dma-names' for DMA client nodes
* Update mxs-dma device tree binding doc
