[GIT PULL] iommu/arm-smmu: updates for 3.17

[Will Deacon]

Hi Joerg,

Please can you pull the following ARM SMMU updates for 3.17?

The main changes are:

 - Removal of unused SMMU chaining code
 - Initial support for PCI masters
 - Misc. non-critical fixes to the capability checking code and TCR
   configuration

This has largely come out of work enabling passthrough of PCI devices
to a KVM virtual machine with VFIO, so I anticipate further patches in
this area in the near future.

Cheers,

Will
