[Intel-gfx] [PATCH] drm/i915: Give the sprite width to the WM computation

In the future, we'll need the height of the fb we're fetching from
memory for WM computation.
At some point in the future, it'd be nice to give a pointer to a
mystical plane_config structure instead of chaplet of parameters.
