drm/i915/skl+: Optimize WM calculation
Plane configuration parameters doesn't change for each WM-level
calculation. Currently we compute same parameters 8 times for each
wm-level.
This patch optimizes it by calculating these parameters in beginning
& reuse during each level-wm calculation.
Changes since V1:
- rebase on top of Rodrigo's series for CNL
