drm/i915: don't disable fdi links harder in ilk_crtc_enable
Because they should have been disabled when shutting down the display pipe previously. To ensure that this is the case, add a few assserts instead of unconditionally disabling the fdi link. Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
