This is a prep series for the actual cdclk refactoring that will be sent following this. Idea is to have a struct - cdclk_step that holds the following: - cdclk action (squash, crawl or modeset) - cdclk frequency which gets populated in atomic check. Driver uses the populated values during atomic commit to do the suitable sequence of actions like programming squash ctl registers in case of squashing or PLL sequence incase of modeset and so on. This series just addresses the initial idea. The actual plumming in the atomic commit phase will be sent shortly.
