[PATCH linux-next] dmaengine: add context parameter fixups

[Alexandre Bounine]

This patch fixes drivers that use device_prep_slave_sg() and
device_prep_dma_cyclic() interfaces and have been missed during the initial
release of interface changing patches.

This patch is based on linux-next-20120322 code tree.
See https://lkml.org/lkml/2012/3/22/339 for build failure report.
