Sricharan R 109bd48ea2 iommu/msm: Add DT adaptation
The driver currently works based on platform data. Remove this
and add support for DT. A single master can have multiple ports
connected to more than one iommu.

                      master
                        |
                        |
                        |
           ------------------------
           |                      |
         IOMMU0                 IOMMU1
           |                      |
      ctx0   ctx1            ctx0   ctx1

This association of master and iommus/contexts were previously
represented by platform data parent/child device details. The client
drivers were responsible for programming all of the iommus/contexts
for the device. Now while adapting to generic DT bindings we maintain the
list of iommus, contexts that each master domain is connected to and
program all of them on attach/detach.

Stephen Boyd 0b559df5ce iommu/msm: Move mach includes to iommu directory
Two header files exist in mach-msm's include/mach directory that
are only used by the MSM iommu driver. Move these files to the
iommu driver directory and prefix them with "msm_". This allows
us to compile the MSM iommu driver on multi-platform kernels.
