dmaengine: xilinx_dma: Set DMA mask for coherent APIs
The xilinx dma driver uses the consistent allocations, so for correct
operation also set the DMA mask for coherent APIs. It fixes the below
kernel crash with dmatest client when DMA IP is configured with 64-bit
address width and linux is booted from high (>4GB) memory.
