[GIT PULL] iommu/arm-smmu: updates for 3.13

[Will Deacon]

Hi Joerg,

Please pull these ARM SMMU updates for 3.13. The bulk of the changes are
from Andreas, who has been having fun running the driver on real hardware. I
expect some additional patches from him in the future to add support for
things like device isolation once we've ironed out the wrinkles in the
current proposals.

I've successfully tested this lot in my modelled environments without any
observed regressions.

Cheers,

Will
