[GIT PULL] slave-dmaengine updates

[Koul, Vinod]

Hi Linus,

Here is the slave-dmaengine updates which include general updates to few drivers and 
start of the consolidation of arm dma drivers into generic dma controllers
This also had dma-slave documentation updated by Russell

The following changes since commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe:
