dmaengine patches

[Sascha Hauer]

Hi,

The following patches are new versions of patches previously
posted with the latest comments from Dan integrated. New
in this series is a dma driver for the older i.MX SoCs. I decided
to implement the dmaengine driver for these SoCs as a user of
the old dma driver. This allows us keep both dma drivers in the
tree and to convert the users of the dma driver smoothly and one
by one to the new driver and remove the old driver afterwards.
