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()`.
