iommu/msm: Make use of iommu_device_register interface

Register the MSM IOMMUs to the iommu core and add sysfs
entries for that driver.

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.

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.
