[GIT PULL] iommu/arm-smmu: Updates for 4.9

[Will Deacon]

Hi Joerg,

Please pull these significant arm-smmu updates for 4.9. The vast majority
of the code here is Robin's series to move the drivers over to the
generic DT bindings, which finally hooks up the DMA API and MSI mapping
for host machines. This has been stewing for a while and is now at the
point where I feel it's much better in mainline than languishing outside.

A consequence of that is that there are some non-trivial changes outside
of the drivers, but these are all acked by the relevant subsystem
maintainers.

Other stuff here includes some non-critical fixes to the queue handling
on SMMUv3 and a small devm cleanup that missed the boat last time around.

Cheers,

Will
