sata_dwc_460ex: device tree may specify dma_channel
sata_dwc_460ex: device tree may specify dma_channel

Only channel 0 is currently support and the driver code is fixed on
channel 0. This patch lets device node specifying dma-channel in case
it is not 0. If no dma-channel property is specified, channel 0 is
used as default.
