drm/i915/skl+: refactor WM calculation for NV12
Current code calculates DDB for planar formats in such a way that we
store DDB of plane-0 in plane 1 & vice-versa.
In order to make this clean this patch refactors WM/DDB calculation for
NV12 planar formats.
v2: Addressed review comments by Maarten
v3: Rebased and addressed review comments by Maarten
v4: Fixed a compilation issue of string replacement is_nv12 to
is_planar
v5: Added reviewed by from Juha-Pekka Heikkila
v6: Rebased the series
