ARM: OMAP2+: Move plat/iovmm.h to include/linux/omap-iommu.h Looks like the iommu framework does not have generic functions exported for all the needs yet. The hardware specific functions are defined in files like intel-iommu.h and amd-iommu.h. Follow the same standard for omap-iommu.h. This is needed because we are removing plat and mach includes for ARM common zImage support. Further work should continue in the iommu framework context as only pure platform data will be communicated from arch/arm/*omap*/* code to the iommu framework.

iommu/omap: Remove virtual memory manager The OMAP3 ISP driver was the only user of the OMAP IOVMM API. Now that is has been ported to the DMA API, remove the unused virtual memory manager.
