Subject: [PATCH 04/14] msm: iommu: Revise GFX3D IOMMU contexts and M2V mappings

Update the platform data for the 3D core's IOMMU based on
the revised usage model. Remove unused contexts and rename
the remaining contexts based on their new function. Add the
new M2VCBMT mappings for the updated contexts.
