ENGR00274585-1 dma: imx-sdma: update sdma to support p2p

For the sake of support asrc p2p, the sdma driver need to be updated.

1. Add another dma_request, p2p need two dma_request.
2. There are some cases which need to change the config after the
dma_request_channel. add dma_request config in dmaengine_slave_config().
3. add dma_request0 and dma_request1 in dma_slave_config for runtime config
in dmaengine_slave_config.
