It's too big to cover these changes. Can you make it more small changes.
1. Remove existing ones since no user at this time.
2. Add new define and data structures.
3. Support new system mmu features based on generic iommu.

It's simple example. The renaming is one candidate patch.

It's exynos4 series clock and don't have gsc name. I don't know LSI
decides to use gsc instead of fimc for both exynos4 and exynos5. but
there's no name gsc at Spec..
