[GIT PULL] dmaengine updates for 4.14-rc1

[Vinod Koul]

Hi Linus,

Here are the updates from dmaengine subsystem for 4.14-rc1. This one
features usual updates to the drivers and one good part of removing DA_SG
from core as it has no users.

The following changes since commit 5771a8c08880cdca3bfb4a3fc6d309d6bba20877:

  Linux v4.13-rc1 (2017-07-15 15:22:10 -0700)

are available in the git repository at:

  git://git.infradead.org/users/vkoul/slave-dma.git tags/dmaengine-4.14-rc1
