[Intel-gfx] [PATCH] drm/i915: Be optimistic about future display engines having 7 WM levels

As we're doing throughout the code, being optimistic that platform n + 1
will mostly reuse the same things as platform n allows us to minimize
the enabling work needed.

This time, it's about the number of WM levels.
