[Intel-gfx] [PATCH 0/6] Introduce struct cdclk_step

[Anusha Srivatsa <anusha.srivatsa@intel.com>]

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.
