dmaengine: xilinx_dma: Correctly handle cyclic descriptor callbacks
DMA clients can provide one of two types of callbacks. For this reason dmaengine drivers should not directly invoke `callback`, but always use `dmaengine_desc_callback_invoke()`. This makes sure that both types of callbacks are handled correctly. The xilinx_dma driver currently doesn't do this for cyclic descriptors and only handles the `callback` type callback. If the client used the `callback_result` type callback it will not be called. Fix this by switching to `dmaengine_desc_callback_valid()` and `dmaengine_desc_callback_invoke()`.
