[Intel-gfx] [PATCH 35/36] drm/i915: drop haswell fdi lane check from intel_crt_mode_valid

[Daniel Vetter]

With the consolidate fdi lane computation and checking in the
pipe_config code we don't need this any more. Furthermore it's
actually not quite correct, since it doesn't take bpp into account.

And if we want to get fdi autodithering going, we can't reject modes
this early.
