Thomas Gessler 8b5fbe08e5 dmaengine: xilinx_dma: Set dma_device directions 
[ Upstream commit 7e01511443 ]

Coalesce the direction bits from the enabled TX and/or RX channels into
the directions bit mask of dma_device. Without this mask set,
dma_get_slave_caps() in the DMAEngine fails, which prevents the driver
from being used with an IIO DMAEngine buffer.
