dmaengine: imx-sdma: Set DMA channel to be private

Browse source 
If async-tx is loaded before device drivers that requires imx-sdma, the
dmaengine_get() routine from async-tx grabs all non-private channels,
so devices that require DMA fail to work.

So mark imx-sdma with DMA_PRIVATE to avoid such situation.
