[PATCH] dmaengine: add slave-dma maintainer

[Dan Williams]

Slave-dma has become the predominant usage model for dmaengine and needs
special attention.  Memory-to-memory dma usage cases will continue to be
maintained by Dan.

Several factors have contributed to the need to add a co-maintainer
to dmaengine.  First my time is being consumed in other areas [1].
Also, after Russell's review of amba-pl08x it became clear that the
semantics of the slave interface need to specified [2].  My work on the
iop-adma and ioatdma drivers has been limited to the memory-to-memory
use cases (NET_DMA and ASYNC_TX_DMA).  Without direct slave-dma api
experience (client driver or dma driver) it is difficult to parse its
needs outside of its base similarities with the memory-to-memory case.

I have asked my colleague, Vinod Koul, to:
1/ put more definition around the slave api and usages to try to ensure 
consistent behavior across drivers (as much as possible)
2/ help review and merge new drivers according to this definition

Vinod wrote the intel_mid_dma driver and expects to be involved with
slave-dma for the foreseeable future.

I will continue to maintain the memory-to-memory and related async_tx 
usages of dmaengine (that need fixing [3]), but it is clear that this
usage has become a secondary role for the dmaengine infrastructure.
