dmaengine: dw-axi-dmac: Set constraint to the Max segment size
Add support for DMA Scatter-Gather (SG) constraint so that DMA clients can
handle the AxiDMA limitation.
Without supporting DMA constraint the default Max segment size reported by
dmaengine is 64KB, which is not supported by Intel KeemBay AxiDMA.
