The rest of the driver started using CONFIG_QCOM_KGSL_IOMMU. The
replayed MMU changes didn't get the memo.

The current MMU code assumes a binary state - either there is a
IOMMU or there isn't. This precludes other memory models and
makes for a lot of inherent IOMMU knowledge in the generic MMU
code and the rest of the driver. Reorganize and cleanup the
MMU and IOMMU code:
* Add a Kconfig boolean dependent on ARM and/or MSM SMMU support.
* Make "nommu" mode an actual MMU subtype and figure out available
MMU subtypes at probe time.
* Move IOMMU device tree parsing to the IOMMU code.
* Move the MMU subtype private structures into struct kgsl_mmu.
* Move adreno_iommu specific functions out of other generic
adreno code.
* Move A4XX specific preemption code out of the ringbuffer code.

Make several changes to build the GPU driver for 4.4:
- Rename CONFIG_MSM to CONFIG_QCOM where applicable
- Add msm_kgsl.h to the Kbuild exports
- Remove linux/coresight_of.h (as it has been merged into
coresight.h) and remove the .owner member of the
coresight_desc struct.
- Use the new location for the sync.h file (in staging)
- Remove an unused sync function
- Move oneshot_sync.h inside of #ifdef wrappers
