IMHO stuff like this will be needed by many SoCs. Some examples of similar things for omaps that have eventually become generic frameworks have been the clock framework, USB OTG support, runtime PM, pinmux framework and so on. So I suggest a minimal generic API from the start as that will make things a lot easier in the long run.
