drm/i915: Use intel state as much as possible in wm code
Instead of directly referencing drm_crtc_state, convert to
intel_ctc_state and use the base struct. This is useful when we're
making the split between uapi and hw state, and also makes the
code slightly more readable.
A lot of places also use cstate, instead of the more common crtc_state.
Clean those up to use crtc_state. Same for pstate vs plane_state. (Ville)
