[PATCH V2 4/6] dmaengine: xilinx_dma: Increase AXI DMA transaction segment count

[Sarath Babu Naidu Gaddam]

From: Radhey Shyam Pandey <radhey.shyam.pandey at xilinx.com>

Increase AXI DMA transaction segments count to ensure that even in
high load we always get a free segment in prepare descriptor for a
DMA_SLAVE transaction.
