dmaengine: axi-dmac: terminate early DMA transfers after a partial one
When a partial transfer is received, the driver should not submit any more segments to the hardware, as they will be ignored/unused until a new transfer start operation is done. This change implements this by adding a new flag on the AXI DMAC descriptor. This flags is set to true, if there was a partial transfer in a previously completed segment. When that flag is true, the TLAST flag is added to the to the submitted segment, signaling the controller to stop receiving more segments.
