[Intel-gfx] [PATCH 02/11] drm/i915: remove padding from struct skl_wm_level

This reduces the size of struct skl_wm_level from 6 to 4, which
reduces the size of struct skl_plane_wm from 104 to 70, which reduces
the size of struct skl_pipe_wm from 524 to 356. A reduction of 168
padding bytes per pipe. This will increase even more the next time we
bump I915_MAX_PLANES.
