[PATCH 2/3] net: xilinx: axienet: use dmaengine_prep_slave_sg_context()

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

Replace the direct call to dma_dev->device_prep_slave_sg() with the
dmaengine_prep_slave_sg_context() helper, which handles NULL checks and
passes the context pointer cleanly.

No functional change. Prepare to make struct dma_device private to the DMA
engine.

Suggest go through DMA engine tree. this is only one of 3 user, which
use context at prep sg.
