4 - compatible : Should be "fsl,<chip>-dma-apbh" or "fsl,<chip>-dma-apbx"
5 - reg : Should contain registers location and length
6 - interrupts : Should contain the interrupt numbers of DMA channels.
7 If a channel is empty/reserved, 0 should be filled in place.
8 - #dma-cells : Must be <1>. The number cell specifies the channel ID.
9 - dma-channels : Number of channels supported by the DMA controller
12 - interrupt-names : Name of DMA channel interrupts
