[PATCH 1/3] dmaengine: xilinx: xdma: Fix wrong offsets in the buffers addresses in dma descriptor

[Louis Chauvet]

From: Miquel Raynal <miquel.raynal at bootlin.com>

The addition of interleaved transfers slightly changed the way
addresses inside DMA descriptors are derived, breaking cyclic
transfers.

Fixes: 3e184e64c2e5 ("dmaengine: xilinx: xdma: Prepare the introduction of interleaved DMA transfers")
