Some of those might be very SoC specific. Eg OMAP doesn't need software
controlled modulereset. I don't think we should add a new function to the
clock framework for clock related features which only exist in a single
SoC or family. Ideally we could use inheritance to add methods to derived
clocktypes, but that's not really possible in C unfortunately.
