dmaengine: sf-pdma: Support of_dma_controller_register()

Update sf-pdma driver to adopt generic DMA device tree bindings.
It calls of_dma_controller_register() with of_dma_xlate_by_chan_id
to get the generic DMA device tree helper support and the DMA
clients can look up the sf-pdma controller using standard APIs.
