[Intel-gfx] [RFC 1/5] Remove unused parameters from intel_plane_wm_parameters

[Matt Roper]

General comment (that applies to the whole series); when you write your
commit message, the first line (which becomes the email subject above)
should be prefixed by "drm/i915:"  If your patch is only modifying the
code for a specific platform, you can include that too when appropriate
(e.g., "drm/i915/skl:").

I think you can leave this line out of your description.  Killing off
dead code / unused fields is worthwhile on its own and doesn't really
need two-level watermarks as justification.
