[CFT] DMA engine patches

[Russell King - ARM Linux]

I am intending to post the _entire_ set of DMA patches I have so far.
I'm going to be doing this in a slightly different way to normal,
because of the way the branches are structured.

What will come first is a set of three common patches to all the
branches.  Following on from that will be the individual sets for
sa11x0, pl08x and OMAP.

These are for testing, and are based on v3.5-rc1.
