Cleanup legacy OMAP IOMMU device creation

Hi Tony,

The following series removes the legacy platform device creation logic for OMAP IOMMU devices. I will cleanup the legacy support from the OMAP IOMMU driver in a subsequent merge window after this series makes it to mainline.

Patches are based on 4.3-rc1 + the OMAP3 ISP instantiation cleanup patch [1]. All the patches need to be picked up sequentially, otherwise a NULL pointer dereference crash might be seen on OMAP3 legacy boots as the dev attribute structure is deferenced directly in mach-omap2/omap-iommu.c during platform data creation. Also, the last patch removes the structure definition altogether, so will cause build issues if picked separately from the hwmod cleanup patches.

I do not have any boards where I can still perform a legacy-style boot, so patches verified using DT-boot only.

regards
Suman

Ping on this series. You should be able to pick up atleast patch 1 if not picking all, now that the OMAP3 ISP cleanup patch is staged in your omap-for-4.4/cleanup branch.
