assert_plane_enabled() is now triggering during FDI link train because
we no longer enable planes that early.
This problem got introduced in:
commit a5c4d7bc187bd13bc11ac06bb4ea3a0d4001aa4d
Author: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

drm/i915: Disable/enable planes as the first/last thing during modeset on ILK+
Just drop the assert since we shouldn't need planes for link training.
