Folker Schwesinger 38433a6fdf dmaengine: xilinx_dma: Support descriptor setup from dma_vecs 
The DMAEngine provides an interface for obtaining DMA transaction
descriptors from an array of scatter gather buffers represented by
struct dma_vec. This interface is used in the DMABUF API of the IIO
framework [1][2].
To enable DMABUF support through the IIO framework for the Xilinx DMA,
implement callback .device_prep_peripheral_dma_vec() of struct
dma_device in the driver.
